+# 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:

+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      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.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      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
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      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.
+
+   END OF TERMS AND CONDITIONS

+   APPENDIX: How to apply the Apache License to your 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

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      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,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      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

+
+      (b) You must cause any modified files to carry prominent notices

+          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.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      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
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      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.
+

+# How to publish new versions
+## Prerequisites
+1. Installed poetry
+```
+pip install poetry
+```
+2. Set up [API tokens](https://pypi.org/help/#apitoken)
+3. Be a collaborator on [pypi](https://pypi.org/project/mgp/)
+
+## Making changes
+1. Make changes to the package
+2. Bump version in `pyproject.tml`
+3. `poetry build`
+4. `poetry publish`
+
+## Why is this not automatized?
+
+Because someone always has to manually bump up the version in `pyproject.toml`
+
+## Why does `_mgp.py` exists?
+Because we are mocking here all the types that are created by Memgraph
+in order to fix typing errors in `mgp.py`.
