-# How to contribute?
-
-This is a general purpose guide for contributing to Memgraph. We're still
-working out the kinks to make contributing to this project as easy and
-transparent as possible, but we're not quite there yet. Hopefully, this document
-makes the process for contributing clear and answers some questions that you may
-have.

-
-## Open development
-
-All work on Memgraph is done via [GitHub](https://github.com/memgraph/memgraph).
-Both core team members and external contributors send pull requests which go
-through the same review process.
-
-## Branch organization
-
-Most pull requests should target the [`master
-branch`](https://github.com/memgraph/memgraph/tree/master). We only use separate
-branches for developing new features and fixing bugs before they are merged with
-`master`. We do our best to keep `master` in good shape, with all tests passing.
-
-Code that lands in `master` must be compatible with the latest stable release.
-It may contain additional features but no breaking changes if it's not
-absolutely necessary. We should be able to release a new minor version from the
-tip of `master` at any time.
-
-## Bugs & changes
-
-### Where to find known issues?
-
-We are using [GitHub Issues](https://github.com/memgraph/memgraph/issues) for
-our public bugs. We keep a close eye on this and try to make it clear when we
-have an internal fix in progress. Before filing a new task, try to make sure
-your problem doesn't already exist.
-
-### Proposing a change
-
-If you intend to change the public API, or make any non-trivial changes to the
-implementation, we recommend [filing an
-issue](https://github.com/memgraph/memgraph/issues/new). This lets us reach an
-agreement on your proposal before you put significant effort into it.
-
-If you're only fixing a bug, it's fine to submit a pull request right away but
-we still recommend to file an issue detailing what you're fixing. This is
-helpful in case we don't accept that specific fix but want to keep track of the
-issue.
-
-### Your first pull request
-
-Working on your first Pull Request? You can learn how from this free video
-series:
-
-**[How to Contribute to an Open Source Project on
-GitHub](https://app.egghead.io/courses/how-to-contribute-to-an-open-source-project-on-github)**
-
-If you decide to fix an issue, please be sure to check the comment thread in
-case somebody is already working on a fix. If nobody is working on it at the
-moment, please leave a comment stating that you intend to work on it so other
-people don't accidentally duplicate your effort.
-
-If somebody claims an issue but doesn't follow up for more than two weeks, it's
-fine to take it over but you should still leave a comment.
-
-### Sending a pull request
-
-The core team is monitoring for pull requests. We will review your pull request
-and either merge it, request changes to it, or close it with an explanation.
-**Before submitting a pull request,** please make sure the following is done:
-
-1. Fork [the repository](https://github.com/memgraph/memgraph) and create your
-   branch from `master`.
-2. If you've fixed a bug or added code that should be tested, add tests!
-3. Use the formatter `clang-format` for C/C++ code and `flake8` for Python code.
-   `clang-format` will automatically detect the `.clang-format` file in the root
-   directory while `flake8` can be used with the default configuration.
-
-### Style guide
-
-Memgraph uses the [Google Style
-Guide](https://google.github.io/styleguide/cppguide.html) for C++ in most of its
-code. You should follow them whenever writing new code.
-
-## How to get in touch?
-
-Aside from communicating directly via Pull Requests and Issues, the Memgraph
-Community [Discord Server](https://discord.gg/memgraph) is the best place for
-conversing with project maintainers and other community members.
-
-## [Code of Conduct](https://github.com/memgraph/memgraph/blob/master/CODE_OF_CONDUCT.md)
-
-Memgraph has adopted the [Contributor
-Covenant](https://www.contributor-covenant.org/) as its Code of Conduct, and we
-expect project participants to adhere to it. Please read [the full
-text](https://github.com/memgraph/memgraph/blob/master/CODE_OF_CONDUCT.md) so
-that you can understand what actions will and will not be tolerated.

+## User Documentation
 
-## :clipboard: Description
+Memgraph user documentation is maintained within
+[docs](https://github.com/memgraph/docs) repository. The documentation is also
+available on [GitBook](https://docs.memgraph.com).
 
-Memgraph is an open source graph database built for real-time streaming and
-compatible with Neo4j. Whether you're a developer or a data scientist with
-interconnected data, Memgraph will get you the immediate actionable insights
-fast.
+## Licences
 
-Memgraph directly connects to your streaming infrastructure. You can ingest data
-from sources like Kafka, SQL, or plain CSV files. Memgraph provides a standard
-interface to query your data with Cypher, a widely-used and declarative query
-language that is easy to write, understand and optimize for performance. This is
-achieved by using the property graph data model, which stores data in terms of
-objects, their attributes, and the relationships that connect them. This is a
-natural and effective way to model many real-world problems without relying on
-complex SQL schemas.
-
-Memgraph is implemented in C/C++ and leverages an in-memory first architecture
-to ensure that you’re getting the [best possible
-performance](http://memgraph.com/benchgraph) consistently and without surprises.
-It’s also ACID-compliant and highly available.
-

-# CSV Import Tool Documentation
-
-CSV is a universal and very versatile data format used to store large quantities
-of data.  Each Memgraph database instance has a CSV import tool installed called
-`mg_import_csv`.  The CSV import tool should be used for initial bulk ingestion
-of data into the database.  Upon ingestion, the CSV importer creates a snapshot
-that will be used by the database to recover its state on its next startup.
-
-If you are already familiar with the Neo4j bulk import tool, then using the
-`mg_import_csv` tool should be easy.  The CSV import tool is fully compatible
-with the [Neo4j CSV
-format](https://neo4j.com/docs/operations-manual/current/tools/import/). If you
-already have a pipeline set-up for Neo4j, you should only replace `neo4j-admin
-import` with `mg_import_csv`.
-
-## CSV File Format
-
-Each row of a CSV file represents a single entry that should be imported into
-the database.  Both nodes and relationships can be imported into the database
-using CSV files.
-
-Each set of CSV files must have a header that describes the data that is stored
-in the CSV files. Each field in the CSV header is in the format
-`<name>[:<type>]` which identifies the name that should be used for that column
-and the type that should be used for that column. The type is optional and
-defaults to `string` (see the following chapter).
-
-Each CSV field must be divided using the delimiter and each CSV field can either
-be quoted or unquoted. When the field is quoted, the first and last character in
-the field *must* be the quote character. If the field isn't quoted, and a quote
-character appears in it, it is treated as a regular character. If a quote
-character appears inside a quoted string then the quote character must be
-doubled in order to escape it. Line feeds and carriage returns are ignored in
-the CSV file, also, the file can't contain a NULL character.
-
-## Properties
-
-Both nodes and relationships can have properties added to them.  When importing
-properties, the CSV importer uses the name specified in the header of the
-corresponding CSV column for the name of the property.  A property is designated
-by specifying one of the following types in the header:
- - `integer`, `int`, `long`, `byte`, `short`: creates an integer property
- - `float`, `double`: creates a float property
- - `boolean`, `bool`: creates a boolean property
- - `string`, `char`: creates a string property
-
-When importing a boolean value, the CSV field should contain exactly the text
-`true` to import a `True` boolean value.  All other text values are treated as a
-boolean value `False`.
-
-If you want to import an array of values, you can do so by appending `[]` to any
-of the above types.  The values of the array are then determined by splitting
-the raw CSV value using the array delimiter character.
-
-Assuming that the array delimiter is `;`, the following example:
-```plaintext
-first_name,last_name:string,number:integer,aliases:string[]
-John,Doe,1,Johnny;Jo;J-man
-Melissa,Doe,2,Mel
-```
-
-Will yield these results:
-```plaintext
-CREATE ({first_name: "John", last_name: "Doe", number: 1, aliases: ["Johnny", "Jo", "J-man"]});
-CREATE ({first_name: "Melissa", last_name: "Doe", number: 2, aliases: ["Mel"]});
-```
-### Nodes
-
-When importing nodes, several more types can be specified in the header of the
-CSV file (along with all property types):
- - `ID`: id of the node that should be used as the node ID when importing
-   relationships
- - `LABEL`: designates that the field contains additional labels for the node
- - `IGNORE`: designates that the field should be ignored
-
-The `ID` field type sets the internal ID that will be used for the node when
-creating relationships.  It is optional and nodes that don't have an ID value
-specified will be imported, but can't be connected to any relationships.  If you
-want to save the ID value as a property in the database, just specify a name for
-the ID (`user_id:ID`).  If you just want to use the ID during the import, leave
-out the name of the field (`:ID`).  The `ID` field also supports creating
-separate ID spaces.  The ID space is specified with the ID space name appended
-to the `ID` type in parentheses (`ID(user)`).  That allows you to have the same
-IDs (by value) for multiple different node files (for example, numbers from 1 to
-N).  The IDs in each ID space will be treated as an independent set of IDs that
-don't interfere with IDs in another ID space.
-
-The `LABEL` field type adds additional labels to the node.  The value is treated
-as an array type so that multiple additional labels can be specified for each
-node.  The value is split using the array delimiter (`--array-delimiter` flag).
-
-### Relationships
-
-In order to be able to import relationships, you must import the nodes in the
-same invocation of `mg_import_csv` that is used to import the relationships.
-
-When importing relationships, several more types can be specified in the header
-of the CSV file (along with all property types):
- - `START_ID`: id of the start node that should be connected with the
-   relationship
- - `END_ID`: id of the end node that should be connected with the relationship
- - `TYPE`: designates the type of the relationship
- - `IGNORE`: designates that the field should be ignored
-
-The `START_ID` field type sets the start node that should be connected with the
-relationship to the end node.  The field *must* be specified and the node ID
-must be one of the node IDs that were specified in the node CSV files.  The name
-of this field is ignored.  If the node ID is in an ID space, you can specify the
-ID space for the in the same way as for the node ID (`START_ID(user)`).
-
-The `END_ID` field type sets the end node that should be connected with the
-relationship to the start node.  The field *must* be specified and the node ID
-must be one of the node IDs that were specified in the node CSV files.  The name
-of this field is ignored.  If the node ID is in an ID space, you can specify the
-ID space for the in the same way as for the node ID (`END_ID(user)`).
-
-The `TYPE` field type sets the type of the relationship.  Each relationship
-*must* have a relationship type, but it doesn't necessarily need to be specified
-in the CSV file, it can also be set externally for the whole CSV file.  The name
-of this field is ignored.
-
-## CSV Importer Flags
-
-The importer has many command line options that allow you to customize the way
-the importer loads your data.
-
-The two main flags that are used to specify the input CSV files are `--nodes`
-and `--relationships`. Basic description of these flags is provided in the table
-and more detailed explainion can be found further down bellow.
-
-
-| Flag                  | Description  |
-|-----------------------| -------------- |
-|`--nodes`                | Used to specify CSV files that contain the nodes to the importer. |
-|`--relationships`        |  Used to specify CSV files that contain the relationships to the importer.|
-|`--delimiter`            | Sets the delimiter that should be used when splitting the CSV fields (default `,`)|
-|`--quote`                | Sets the quote character that should be used to quote a CSV field (default `"`)|
-|`--array-delimiter`      | Sets the delimiter that should be used when splitting array values (default `;`)|
-|`--id-type`              | Specifies which data type should be used to store the supplied <br /> node IDs when storing them as properties (if the field name is supplied). <br /> The supported values are either `STRING` or `INTEGER`. (default `STRING`)|
-|`--ignore-empty-strings` | Instructs the importer to treat all empty strings as `Null` values  <br /> instead of an empty string value (default `false`)|
-|`--ignore-extra-columns` | Instructs the importer to ignore all columns (instead of raising an error) <br /> that aren't specified after the last specified column in the CSV header. (default `false`) |
-| `--skip-bad-relationships`| Instructs the importer to ignore all relationships (instead of raising an error) <br /> that refer to nodes that don't exist in the node files. (default `false`) |
-|`--skip-duplicate-nodes`  | Instructs the importer to ignore all duplicate nodes (instead of raising an error).  <br /> Duplicate nodes are nodes that have an ID that is the same as another node that was already imported. (default `false`) |
-| `--trim-strings`| Instructs the importer to trim all of the loaded CSV field values before processing them further. <br /> Trimming the fields removes all leading and trailing whitespace from them. (default `false`) |
-
-The `--nodes` and  `--relationships` flags are used to specify CSV files that
-contain the nodes and relationships to the importer.  Multiple files can be
-specified in each supplied `--nodes` or `--relationships` flag. Files that are
-supplied in one `--nodes` or `--relationships` flag are treated by the CSV
-parser as one big CSV file.  Only the first line of the first file is parsed for
-the CSV header, all other files (and rows) are treated as data.  This is useful
-when you have a very large CSV file and don't want to edit its first line just
-to add a CSV header.  Instead, you can specify the header in a separate file
-(e.g. `users_header.csv` or `friendships_header.csv`) and have the data intact
-in the large file (e.g. `users.csv` or `friendships.csv`).  Also, you can supply
-additional labels for each set of node files.
-
-The format of `--nodes` flag is:
-`[<label>[:<label>]...=]<file>[,<file>][,<file>]...`.  Take note that only the
-first `<file>` part is mandatory, all other parts of the flag value are
-optional. Multiple `--nodes` flags can be supplied to describe multiple sets of
-different node files.  For the importer to work, at least one `--nodes` flag
-*must* be supplied.
-
-The format of `--relationships` flag is: `[<type>=]<file>[,<file>][,<file>]...`.
-Take note that only the first `<file>` part is mandatory, all other parts of the
-flag value are optional.  Multiple `--relationships` flags can be supplied to
-describe multiple sets of different relationship files.  The `--relationships`
-flag isn't mandatory.
-
-## CSV Parser Logic
-
-The CSV parser uses the same logic as the standard Python CSV parser.  The data
-is parsed in the same way as the following snippet:
-
-```python
-import csv
-for row in csv.reader(stream, strict=True):
-    # process 'row'
-```
-
-Python uses 'excel' as the default dialect when parsing CSV files and the
-default settings for the CSV parser are:
- - delimiter: `','`
- - doublequote: `True`
- - escapechar: `None`
- - lineterminator: `'\r\n'`
- - quotechar: `'"'`
- - skipinitialspace: `False`
-
-The above snippet can be expanded to:
-
-```python
-import csv
-for row in csv.reader(stream, delimiter=',', doublequote=True,
-                      escapechar=None, lineterminator='\r\n',
-                      quotechar='"', skipinitialspace=False,
-                      strict=True):
-    # process 'row'
-```
-

+
+ - GCC $GCC_VERSION

+ - GDB $GDB_VERSION
+ - CMake $CMAKE_VERSION
+ - Cppcheck $CPPCHECK_VERSION
+ - LLVM (Clang, LLD, compiler-rt, Clang tools extra) $LLVM_VERSION

+## Required libraries
+
+In order to be able to run all of these tools you should install the following

+    procedures. The registered `func` needs to be a callable which optionally
+    takes `ProcCtx` as the first argument. Other arguments of `func` will be
+    bound to values passed in the cypherQuery. The full signature of `func`
+    needs to be annotated with types. The return type must be
+    `Record(field_name=type, ...)` and the procedure must produce either a
+    complete Record or None. To mark a field as deprecated, use
+    `Record(field_name=Deprecated(type), ...)`. Multiple records can be
+    produced by returning an iterable of them. Registering generator functions
+    is currently not supported.
+
+    Example usage.
+
+    ```
+    import mgp
+
+    @mgp.read_proc
+    def procedure(context: mgp.ProcCtx,
+                  required_arg: mgp.Nullable[mgp.Any],

+        # Multiple rows can be produced by returning an iterable of mgp.Record
+        return mgp.Record(args=args, result='Hello World!')
+    ```
+
+    The example procedure above returns 2 fields: `args` and `result`.
+      * `args` is a copy of arguments passed to the procedure.
+      * `result` is the result of this procedure, a "Hello World!" string.
+    Any errors can be reported by raising an Exception.
+
+    The procedure can be invoked in openCypher using the following calls:
+      CALL example.procedure(1, 2) YIELD args, result;
+      CALL example.procedure(1) YIELD args, result;
+    Naturally, you may pass in different arguments or yield less fields.

+
+1.2. "Confidential Information" means all information disclosed
+by a party ("Disclosing Party") to the other party ("Receiving Party"), whether
+orally or in writing, that is designated as confidential or that reasonably
+should be understood to be confidential given the nature of the information and
+the circumstances of disclosure. Customer's Confidential Information includes
+Customer Data; Memgraph Confidential Information includes the Software and
+Services; and Confidential Information of each party includes the terms and
+conditions of this Agreement and all Orders (including pricing), as well as
+business and marketing plans, technology and technical information, product
+plans and designs, and business processes disclosed by such party. However,
+Confidential Information does not include any information that (i) is or
+becomes generally known to the public without breach of any obligation owed to
+the Disclosing Party, (ii) was known to the Receiving Party prior to its
+disclosure by the Disclosing Party without breach of any obligation owed to the
+Disclosing Party, (iii) is received from a third party without breach of any
+obligation owed to the Disclosing Party, or (iv) was independently developed by
+the Receiving Party.
+
+1.3. "Customer Data" means business information or other data loaded by or for
+Customer and/or processed by the Software.
+
+1.4. "Data Protection Legislation" means all applicable data protection and
+privacy legislation in force from time to time in the UK including the General
+Data Protection Regulation ((EU) 2016/679); the Data Protection Act 2018; the

+Directive 2009/136/EC) and the Privacy and Electronic Communications
+Regulations 2003 (SI 2003/2426) as amended.
+
+1.5. "Order Document" or "Order" means an order on the Memgraph form of
+provisioning document that is submitted by or on behalf of Customer, and
+executed by or on behalf of the parties referencing this Agreement and that
+specifies the Software and/or Services ordered by Customer, as well as the
+specific terms and conditions, for that particular transaction.
+
+1.6. "Services" means those services, including Support Services, which may be
+provided to Customer by Memgraph pursuant to the terms of this Agreement and
+are expressly limited to those services directly related to Customer's use of
+the Software, and expressly exclude any other services.
+
+1.7. "Software" means the Memgraph proprietary downloadable graph database
+enterprise software ("Enterprise Software") and the associated technical
+documentation located at https://docs.memgraph.com/ ("Documentation"), as well
+as software updates, upgrades, bug fixes, or modified versions thereof that
+Memgraph licenses or provides to Customer directly or indirectly throughout the
+Subscription Term.
+
+1.8. "Subscription Term" means the fixed term, of not less than one (1) year,
+designated in an Order Document beginning on the Effective Date and ending at
+the end of the period stated therein. If no expiration date is specified in an
+Order Document, the Subscription Term shall be a one (1) year period ("Minimum
+Subscription Term"). A "Subscription" is the binding, non-cancellable contract
+for the use of the Software for the Subscription Term as set forth in an Order
+Document.

+pursuant to the terms of this Agreement.
+
+## 2. ORDERS, DELIVERY; SUPPORT.
+
+2.1. Delivery. Memgraph will promptly deliver the Software after it accepts an
+Order and Customer issues a purchase order referencing such Order. Unless
+otherwise stated in an Order, Customer is solely responsible for installing
+Software on Customer's own computer equipment. In some instances, Customer's
+purchasing relationship exists solely between Customer and an authorised
+reseller of Memgraph's Software and Services (a "Reseller"), in which case
+Sections 5.1-5.3 (Fees and Payment) will be inapplicable to such Order(s), and
+the Reseller shall be responsible for submitting Orders and the appropriate
+payment method therewith to Memgraph. An Order is not binding until Memgraph
+accepts and countersigns the Order.
+
+2.2 Support. Memgraph will use commercially reasonable efforts to provide
+Support to Customer in accordance with Memgraph's then-current terms and
+conditions set forth at
+https://download.memgraph.com/legal/memgraph-support-terms-and-conditions.pdf
+at the support tier stated in the applicable Order. The Support terms and
+conditions are subject to change at Memgraph's discretion; however, Memgraph
+will not materially reduce the level of Support during a Subscription Term for
+which Fees have been paid.
+
+## 3. LICENCE GRANTS; RESTRICTIONS AND PROPRIETARY RIGHTS.
+
+Customer's licence and access rights and benefits and Memgraph's obligations to
+Customer will vary depending on the product and the type of licence Memgraph is
+granting. If you purchased a licence to Memgraph Software, your licence will be
+subject to certain use and/or capacity restrictions, as identified on the
+applicable Order Document.
+
+3.1. Enterprise Software Licence. In consideration of the Fees paid hereunder
+and subject to the terms of this Agreement and the applicable Order, Memgraph
+grants Customer a world-wide, non-exclusive, non-transferable,
+non-sublicenseable, and limited licence during the applicable Subscription
+Term, to install, and use the Enterprise Software up to the maximum capacity
+("Licensed Capacity"), and subject to the usage rules, specified in the
+applicable Order Document, and to use Documentation solely for Customer's
+internal business purposes in connection with operation of the Enterprise
+Software.
+
+3.2. Enterprise Trial Licence. If the Customer downloads, accesses, or uses the
+Software under a trial licence ("Trial Licence"), then Customer may use one (1)
+copy of the Software in accordance with the terms and conditions of this
+Agreement for a thirty (30) day period, or such longer trial period represented
+by the applicable licence key issued by or expressly authorised by Memgraph
+(the "Trial Period"). Trial Licences are permitted solely for Customer's
+evaluation use to determine whether to purchase a Subscription to the Software.
+Customer may not use a Trial Licence for any other purpose. At the end of the
+Trial Period, the Trial Licence will expire (and this Agreement will terminate
+as to such Licence and continue to apply to any subsequent Subscription or use
+of the Software; if Customer decides not to obtain a Subscription upon
+expiration of the Trial Period, it will promptly cease using and will delete
+the Software from its computer systems. Memgraph has the right to terminate a
+Trial Licence at any time for any reason.
+
+3.3. NO OBLIGATIONS. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT
+OR IN ANY ORDER DOCUMENT, MEMGRAPH WILL HAVE NO WARRANTY, INDEMNITY, SUPPORT,
+OR SERVICE LEVEL, OBLIGATIONS WITH RESPECT TO ANY ENTERPRISE TRIAL, OR OTHER
+NO-CHARGE SOFTWARE (INCLUDING TOOLS AND UTILITIES) LICENCES.
+
+3.4. General Restrictions. Customer acknowledges that the Software, and its
+structure, organization, and source code, constitute Memgraph's and its
+suppliers' valuable trade secrets, and that usage of the Software is subject to
+the following restrictions:
+
+3.4.1. Restrictions. Customer agrees not to, and not to authorize any third
+party to: (i) allow access or use of the Software by anyone other than its
+Users; (ii) distribute, embed, sell, rent, transfer, lease, lend, sublicense,
+loan, assign, pledge, grant a security interest in, or otherwise make the
+Software accessible or available to any third party; except to the limited
+extent expressly provided in Section 3.4.2, use the Software in any
+service-bureau, timesharing, outsourcing or similar arrangement; or (iii)
+disassemble, decompile, reverse engineer or otherwise attempt to derive the
+structure, sequence or organization of source code or APIs; (iv) remove or
+alter product identification, copyright, trademark or other proprietary
+markings contained in or on the Software; (v) modify, adapt, recast, transform
+or otherwise prepare a derivative work of the Software or portion thereof; (vi)
+conduct any competitive analysis, publish or share with any third party any
+results of any technical evaluation or tests performed on the Software, or
+disclose Software features, errors or bugs to a third party without Memgraph's
+prior written consent; or (vii) engage in any act designed to circumvent any
+restriction set forth in this Agreement, in the Software, or in an Order,
+including but not limited to restrictions related to Licensed Capacity.
+
+3.4.2. Internal Use Licences; Users. The Software is licensed for Customer's
+internal business use and not for distribution or use by third parties. For
+clarity, however, Customer may make available to third parties any
+Customer-hosted services or other Customer applications or services that make
+use of or incorporate the Software, provided and solely to the extent that (i)
+Customer's application or hosted service adds primary and significant
+functionality to the Software, (ii) Customer does not embed or otherwise
+distribute the Software to third parties, (iii) Customer does not provide third
+parties direct access to operate or control the Software itself; and (iv)
+Customer at all times remains in compliance with the terms of the applicable
+licence grants under this Agreement. Subject to the terms and conditions of
+this Agreement, in addition to Customer's employees, Customer may permit its
+independent contractors and consultants ("Contractors") to serve as Users.
+Customer will remain responsible for compliance by each of its Users (including
+but not limited to any Contractor Users) with all of the terms and conditions
+of this Agreement, and any use of the Software by any Contractors must be for
+the sole benefit of Customer.
+
+3.5. Ownership; Reservation of Rights. This is an agreement for use of Memgraph
+Software and not an agreement for sale. Customer acknowledges that it is
+obtaining only a limited right to use the Software on a licensed basis, and
+that irrespective of any use of the words "purchase", "sale" or like terms
+hereunder no ownership rights are being conveyed to Customer. Customer agrees
+that Memgraph or its suppliers retain all right, title and interest (including
+all patent, copyright, trade secret and other intellectual property rights) in
+and to the Memgraph Software. Nothing in this Section shall be deemed as
+granting Memgraph ownership of Customer Data or in any way impacting Customer's
+ownership of Customer Data.
+
+3.6. Third Party Code. The Software may contain or be provided with components
+which are licensed from third parties, including components subject to the
+terms and conditions of "open source" software licences ("Open Source
+Software"). Open Source Software may be identified in the Software,
+Documentation, or in a list of the Open Source Software provided to you upon
+your written request. To the extent required by the licence that accompanies
+the Open Source Software, the terms of such licence will apply in lieu of the
+terms of this Agreement with respect to such Open Source Software, including,
+without limitation, any provisions governing access to source code,
+modification, or reverse engineering.
+
+3.7. IP Ownership. The Parties agree that neither party shall gain, by virtue
+of this Agreement, any rights of ownership or any other interest, right or
+title of copyrights, patents, trade secrets, trademarks, or any other
+intellectual property rights owned by the other Party. Any and all new works
+developed in the course of performing obligations pursuant to this Agreement
+and all new inventions, innovations or ideas developed by a Party in the course
+of performance of its activities under this Agreement, will belong to that
+Party who develops the same. Notwithstanding anything to the contrary in this
+Section, the Parties understand and agree that any and all proprietary
+materials developed by a Party prior to this Agreement and any modifications,
+enhancements, improvements or inventions made to such proprietary materials
+shall be owned by that Party, regardless of which Party prepared or developed
+such modifications, enhancements, improvements or inventions.
+
+## 4. CUSTOMER DATA; OBLIGATIONS OF CUSTOMER AND MEMGRAPH.
+
+4.1. Customer shall retain all of its rights, title, and interest in and to its
+intellectual property rights in Customer Data. Customer grants to Memgraph a
+non-exclusive, worldwide, limited-term licence solely to host, copy, transmit
+and display Customer Data as reasonably necessary for Memgraph to support
+Customer's use of the Software, to ensure the security of and to administrate
+the Software, and to deliver Services in accordance with this Agreement or as
+otherwise outlined in https://memgraph.com/legal/privacy-policy/.
+
+4.2. Protection of Customer Data. Memgraph will maintain appropriate
+administrative, physical, and technical safeguards, consistent with generally
+prevailing industry standards, for protection of the security, confidentiality,
+and integrity of Customer Data, as described in the Documentation. Those
+safeguards will include, but will not be limited to, measures for preventing
+access, use, modification, or disclosure of Customer Data by Memgraph
+personnel, except as permitted by this Agreement.
+
+4.3. Personal data. Both parties will comply with all applicable requirements
+of the Data Protection Legislation. This section 4 is in addition to, and does
+not relieve, remove or replace, a party's obligations under the Data Protection
+Legislation. Notwithstanding the foregoing, the parties acknowledge that, in
+the ordinary course of providing the Services, Memgraph shall not process
+personal data (as defined in the Data Protection Legislation) on behalf of the
+Customer. In the event that the Customer requires Memgraph to process personal
+data on its behalf, it shall notify Memgraph and the parties shall execute such
+terms as necessary under applicable law.
+
+## 5. FEES AND PAYMENT.
+
+5.1. Fees. Customer will pay Memgraph the fees for the Licences and Services as
+set forth in the applicable Order ("Fees"). Customer acknowledges and agrees
+that if Customer's use of the Software exceeds the Licensed Capacity set forth
+on the applicable Orders or otherwise requires the payment of additional fees
+(per the terms of this Agreement), Customer shall be invoiced for such usage
+and Customer agrees to pay the additional fees in accordance with this Section.
+Notwithstanding the terms of Section 5.4 below (Reconciliation), Customer
+acknowledges and agrees that it is obligated to ensure that its Software usage
+does not exceed the Licensed Capacity and to promptly notify Memgraph of any
+such excess usage no more than thirty (30) days from the last day of the
+calendar month during which such excess usage occurred.
+
+5.2. Payment Terms. Except as otherwise specifically set forth on an Order
+Document, all fees are due and payable within thirty days after the date of
+invoice. Renewal Fees for any renewal Subscription Term (if purchased by
+Customer) will be due and payable within thirty (30) days of expiration of the
+then-current term. If Fees are not paid when due, or in the event of other
+breach of this Agreement, Customer shall discontinue use of the Software and
+Memgraph may suspend its performance, including its delivery of technical
+support of the Software or other Services without further notice and without
+penalty. All Orders (including multi-year Subscriptions with annual payment
+schedules) are non-cancellable and all amounts paid are non-refundable, unless
+otherwise expressly set forth herein. Any invoiced amount not received by the
+due date will accrue late interest at the rate of 1.5% of the outstanding
+balance per month, or the maximum rate permitted by applicable law, whichever
+is lower.
+
+5.3. Taxes. Fees are exclusive of taxes. Customer will pay any sales, use,
+value added, duties, fees and other governmental assessments or charges arising
+out of this Agreement and the transactions contemplated herein. Customer will
+make all payments free and clear of, and without reduction for, any withholding
+taxes.
+
+5.4. Reconciliation. At Memgraph's request from time to time, not exceeding
+once per quarter, Customer will provide Memgraph with a report detailing its
+use of the Software, including its non-production and/or production use and
+using the self-monitoring capabilities of the Software or other means, and
+Memgraph may inspect Customer's records related to such report not more
+frequently than annually to ensure payment of Fees. Any on-site review will be
+conducted during regular business hours at Customer's offices. The parties will
+use reasonable good faith efforts to promptly resolve any discrepancies between
+licensed usage and actual usage.
+
+## 6. APPLICABLE LAWS.
+
+6.1. Each Party shall perform this Agreement in accordance with all Applicable
+Laws. Without prejudice to the foregoing, each Party shall:
+
+6.1.1. comply with all Applicable Laws relating to anti-bribery,
+anti-corruption, anti-slavery and human trafficking, including the Bribery Act
+2010 and the Modern Slavery Act 2015 (the "Relevant Requirements");
+
+6.1.2. have and maintain in place throughout the Term its own policies and

+which has a connection with this Agreement.
+
+## 7. REPRESENTATIONS AND WARRANTIES.
+
+7.1. Mutual Representations and Warranties. Each Party represents and warrants
+to the other that: (i) it is a corporation lawfully incorporated and validly
+existing pursuant to the laws of its place of incorporation; (ii) it has all
+requisite power and authority, corporate or otherwise, to execute, deliver and
+perform its obligations under this Agreement; and (iii) this Agreement
+constitutes its legal, valid and binding obligations and may be enforced
+against it.
+
+7.2. Limited Memgraph Warranty; Remedies. Memgraph warrants that the Software,
+when used as permitted hereunder, will operate in all material respects as
+described in the applicable Documentation, and that Services will be provided
+in a professional manner consistent with industry standards.
+
+7.3. Limitations; Remedy. Memgraph does not warrant that the Software or the
+Services will be error-free, uninterrupted or meet Customer's specific
+requirements or that performance of the Services will be uninterrupted.
+Memgraph will have no warranty obligation under Section 7.2 for Customer's
+misuse or failure to use the Software in accordance with its Documentation or
+this Agreement. Customer's sole and exclusive remedy, and Memgraph's sole and
+exclusive obligation, for breach of warranty will be (i) during the thirty (30)
+day period following initial Delivery of the Software under an Order,
+Memgraph's correction of the program errors that cause the breach of warranty,
+or if Memgraph cannot substantially correct such breach in a commercially
+reasonable manner, a refund of the fees paid for the nonconforming Software
+(ii) during the remainder of the relevant Subscription Term, Memgraph's
+delivery of Support with respect to any such program errors. In the event of a
+refund remedy, Customer's licences and right to use the Software or receive
+Services will end. In the event of any noticed breach of warranty with respect
+to Services, Memgraph's sole and exclusive obligation shall be the
+re-performance of the deficient Services.
+
+7.4. Disclaimer. THIS SECTION 7 IS A LIMITED WARRANTY AND, EXCEPT EXPRESSLY AS
+SET FORTH IN SECTION 7.2, THE SOFTWARE, INCLUDING WITHOUT LIMITATION THE
+THIRD-PARTY CODE, AND ALL SERVICES ARE PROVIDED "AS IS". MEMGRAPH MAKES NO
+OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+AND DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
+PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
+
+## 8. INDEMNIFICATION.
+
+8.1. By Memgraph. Memgraph will defend against any action against Customer
+brought by a third party to the extent the action is based on a claim that the
+Software infringes a third party's patent, copyright or trademark (a "Claim")
+and indemnify Customer from the damages, liabilities, costs and expenses
+(including reasonable attorneys' fees) awarded against Customer or agreed in
+settlement by Customer resulting from such Claim. If your use of the Software
+is (or in Memgraph's opinion likely to be) enjoined, then Memgraph may, at its
+own expense and at its option: (i) substitute substantially similar
+functionality for the Software which renders it non-infringing; (ii) procure
+for Customer the right to continue to use the Software; or if (i) and (ii) are
+not commercially reasonable, terminate this Agreement and refund Customer any
+prepaid, unused (pro-rated) Fees for the duration of the then-current
+Subscription Term. The foregoing obligations of Memgraph will not apply: (i) if
+the Software is modified by any party other than Memgraph, but solely to the
+extent the alleged infringement is caused by such modification; (ii) if the
+Software is used in combination with other products or processes not provided
+or authorized by Memgraph, but solely to the extent the alleged infringement is
+caused by such combination; (iii) use of any version or release of Software
+other than the most current version or release made available to Customer by
+Memgraph, if its use would have avoided the infringement; (iv) any unauthorized
+use of the Software. THIS SECTION 8.1 SETS FORTH MEMGRAPH'S SOLE LIABILITY AND
+CUSTOMER'S SOLE AND EXCLUSIVE REMEDY WITH RESPECT TO ANY CLAIM OF INTELLECTUAL
+PROPERTY INFRINGEMENT.
+
+8.2. By Customer. Customer will indemnify and hold Memgraph and its suppliers
+harmless against any claims, liabilities, costs, and expenses (including
+reasonable attorneys' fees) that Memgraph or its suppliers may incur as a
+result of a third-party claim arising from or related to Customer Data, or
+misuse or unauthorised use of the Software by Customer or any User.
+
+8.3. Conditions. All defence and indemnity obligations under Sections 8.1 and
+8.2 are conditioned on the indemnitee (i) giving the indemnitor written notice
+of the relevant claim within thirty (30) days after the indemnitee receives
+notice of the Claim (or sooner if required by applicable law); (ii) reasonably
+cooperating with the indemnitor, at the indemnitor's expense, in the defence of
+the claim; and (iii) giving the indemnitor sole control of the defence and any
+settlement negotiations. The indemnitee may participate in the defence at its
+expense.
+
+## 9. LIMITATION OF LIABILITY.
+
+9.1. TO THE EXTENT PERMITTED BY LAW, NEITHER MEMGRAPH NOR CUSTOMER SHALL BE
+LIABLE TO THE OTHER OR ANY THIRD PARTY FOR LOST PROFITS (WHETHER DIRECT OR
+INDIRECT) OR LOSS OF USE OR DATA, SUBSTITUTE GOODS OR SERVICES, OR FOR
+INCIDENTAL, CONSEQUENTIAL, PUNITIVE, SPECIAL OR EXEMPLARY DAMAGES (INCLUDING
+DAMAGE TO BUSINESS, REPUTATION OR GOODWILL), OR INDIRECT DAMAGES OF ANY TYPE
+HOWEVER CAUSED, WHETHER BY BREACH OF WARRANTY, BREACH OF CONTRACT, IN TORT
+(INCLUDING NEGLIGENCE) OR ANY OTHER LEGAL OR EQUITABLE CAUSE OF ACTION EVEN IF
+SUCH PARTY HAS BEEN ADVISED OF SUCH DAMAGES IN ADVANCE OR IF SUCH DAMAGES WERE
+FORESEEABLE.
+
+9.2. LIMITATIONS ON DIRECT DAMAGES. EXCEPT FOR ANY EXCLUDED CLAIMS AND ANY
+DAMAGES THAT CANNOT BE LIMITED UNDER APPLICABLE LAW, IN NO EVENT WILL
+MEMGRAPH'S TOTAL AGGREGATE LIABILITY ARISING FROM OR RELATED TO THIS AGREEMENT,
+EXCEED AN AMOUNT EQUAL TO THE TOTAL AMOUNT OF FEES PAID OR PAYABLE BY CUSTOMER
+TO MEMGRAPH UNDER THIS AGREEMENT DURING THE TWELVE MONTHS PRECEDING THE CLAIM.
+THE FOREGOING LIMITATIONS SHALL NOT APPLY TO: (i) PAYMENTS TO A THIRD PARTY
+ARISING FROM A PARTY'S OBLIGATIONS UNDER SECTION 8 (INDEMNIFICATION); (ii)
+BREACH BY A PARTY OF SECTION 10 (CONFIDENTIAL INFORMATION), AND (iii)
+INFRINGEMENT BY A PARTY OF THE OTHER PARTY'S INTELLECTUAL PROPERTY RIGHTS
+(COLLECTIVELY EXCLUSIONS (i)-(iii) ARE REFERRED TO AS THE "EXCLUDED CLAIMS").
+WITH RESPECT TO ANY EXCLUDED CLAIMS, MEMGRAPH'S TOTAL AGGREGATE LIABILITY SHALL
+IN NO EVENT EXCEED £1,000,000.
+
+9.3. Nothing in this Agreement excludes the liability of Memgraph for death or
+personal injury caused by the Supplier's negligence; or for fraud or fraudulent
+misrepresentation.
+
+## 10. CONFIDENTIALITY.
+
+10.1. The Receiving Party will use the same degree of care that it uses to
+protect the confidentiality of its own confidential information of like kind
+(but not less than reasonable care) to (i) not use any confidential information
+of the Disclosing Party for any purpose outside the scope of this agreement and
+(ii) except as otherwise authorized by the Disclosing Party in writing, limit
+access to confidential information of the Disclosing Party to those of its and
+its affiliates' employees and contractors who need that access for purposes
+consistent with this agreement and who have signed confidentiality agreements
+with the receiving party containing protections not materially less protective
+of the confidential information than those herein. Neither party will disclose
+the terms of this agreement or any Orders to any third-party other than its
+affiliates, legal counsel, and accountants without the other party's prior
+written consent, provided that a party that makes any such disclosure to its
+affiliate, legal counsel or accountants will remain responsible for such
+affiliate's, legal counsel's, or accountant's compliance with this
+"confidentiality" section.
+
+10.2. Compelled Disclosure. The Receiving Party may disclose confidential
+information of the Disclosing Party to the extent compelled by law to do so,
+provided the Receiving Party gives the Disclosing Party prior notice of the
+compelled disclosure (to the extent legally permitted) and reasonable
+assistance, at the Disclosing Party's cost, if the Disclosing Party wishes to
+contest the disclosure. If the receiving party is compelled by law to disclose
+the Disclosing Party's confidential information as part of a civil proceeding
+to which the Disclosing Party is a party, and the Disclosing Party is not
+contesting the disclosure, the Disclosing Party will reimburse the Receiving
+Party for its reasonable cost of complying and providing secure access to that
+confidential information.
+
+## 11. TERMINATION.

+court" did not appear in sections 123(1)(e) or 123(2) of the Insolvency Act
+1986; or
+
+11.3.2. the other party commences negotiations with all or any class of its
+creditors with a view to rescheduling any of its debts, or makes a proposal for
+or enters into any compromise or arrangement with its creditors other than for
+the sole purpose of a scheme for a solvent amalgamation of that other party
+with one or more other companies or the solvent reconstruction of that other
+party; or
+
+11.3.3. a petition is filed, a notice is given, a resolution is passed, or an

+other party with one or more other companies or the solvent reconstruction of
+that other party; or
+
+11.3.4. an application is made to court, or an order is made, for the

+or
+
+11.3.8. any event occurs, or proceeding is taken, with respect to the other
+party in any jurisdiction to which it is subject that has an effect equivalent
+or similar to any of the events mentioned in clause 11.3.1 to clause 11.3.7
+(inclusive); or
+
+11.3.9. the other party suspends or ceases, or threatens to suspend or cease,
+carrying on all or a substantial part of its business.
+
+11.4. Effect of Termination. Upon the termination of this Agreement: (i) all
+licences will terminate; (ii) Customer will immediately discontinue all use of

+hereunder, and permanently erase, delete, or destroy such Confidential
+Information as soon as permissible under such policy or order.

+# manually specify a version override and then the supplied version will be
+# used instead of the version determined by `git`. All versions (automatically
+# detected and manually specified) can have a custom version suffix added to
+# them.
+#
+# The current version can be one of either:
+#   - release version
+#   - development version
+#
+# The release version is either associated with a `release/X.Y` branch
+# (automatic detection) or is manually specified. When the version is
+# automatically detected from the branch a `.0` is appended to the version.
+# Example 1:
+#   - branch: release/0.50
+#   - version: 0.50.0
+# Example 2:
+#   - manually supplied version: 0.50.1
+#   - version: 0.50.1
+#
+# The development version is always determined using `git` in the following
+# way:
+#   - release version - nearest (older) `release/X.Y` branch version
+#   - distance from the release branch - Z commits
+#   - the current commit short hash
+# Example:
+#   - release version: 0.50.0 (nearest older branch `release/0.50`)

+#   - current commit short hash: 7e1eef94

+# The script then uses the collected information to generate the versions that
+# will be used in the binary, DEB package and RPM package.  All of the versions
+# have different naming conventions that have to be met and they differ among
+# each other.
+#
+# The binary version is determined using the following two templates:
+#   Release version:
+#     <VERSION>-<OFFERING>[-<SUFFIX>]
+#   Development version:
+#     <VERSION>+<DISTANCE>~<SHORTHASH>-<OFFERING>[-<SUFFIX>]

+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+
+      "Source" form shall mean the preferred form for making modifications,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
