-# Galaxy python plugin API
+# GOG Galaxy Integrations Python API
 
-## Usage
+This Python library allows developers to easily build community integrations for various gaming platforms with GOG Galaxy 2.0.
 
-Implement plugin:
+- refer to our <a href='https://galaxy-integrations-python-api.readthedocs.io'>documentation</a>
+
+## Features
+
+Each integration in GOG Galaxy 2.0 comes as a separate Python script and is launched as a separate process that needs to communicate with the main instance of GOG Galaxy 2.0.
+
+The provided features are:
+
+- multistep authorization using a browser built into GOG Galaxy 2.0
+- support for GOG Galaxy 2.0 features:
+  - importing owned and detecting installed games
+  - installing and launching games
+  - importing achievements and game time
+  - importing friends lists and statuses
+  - importing friends recommendations list
+  - receiving and sending chat messages
+- cache storage
+
+## Platform Id's
+
+Each integration can implement only one platform. Each integration must declare which platform it's integrating.
+
+[List of possible Platform IDs](PLATFORM_IDs.md)
+
+## Basic usage
+
+Each integration should inherit from the :class:`~galaxy.api.plugin.Plugin` class. Supported methods like :meth:`~galaxy.api.plugin.Plugin.get_owned_games` should be overwritten - they are called from the GOG Galaxy client at the appropriate times.
+Each of those methods can raise exceptions inherited from the :exc:`~galaxy.api.jsonrpc.ApplicationError`.
+Communication between an integration and the client is also possible with the use of notifications, for example: :meth:`~galaxy.api.plugin.Plugin.update_local_game_status`.
 
 ```python
-import asyncio
-from galaxy.api.plugin import Plugin
+import sys
+from galaxy.api.plugin import Plugin, create_and_run_plugin
+from galaxy.api.consts import Platform
+from galaxy.api.types import Authentication, Game, LicenseInfo, LicenseType
+
 
 class PluginExample(Plugin):
+    def __init__(self, reader, writer, token):
+        super().__init__(
+            Platform.Test,  # choose platform from available list
+            "0.1",  # version
+            reader,
+            writer,
+            token
+        )
+
     # implement methods
+
+    # required
     async def authenticate(self, stored_credentials=None):
-        pass
+        return Authentication('test_user_id', 'Test User Name')
+
+    # required
+    async def get_owned_games(self):
+        return [
+            Game('test', 'The Test', None, LicenseInfo(LicenseType.SinglePurchase))
+        ]
+
+
+def main():
+    create_and_run_plugin(PluginExample, sys.argv)
 
 # run plugin event loop
 if __name__ == "__main__":
-    asyncio.run(MockPlugin().run())
+    main()
 ```
 
-Use [pyinstaller](https://www.pyinstaller.org/) to create plugin executbale.
+## Deployment
 
-## Development
+The client has a built-in Python 3.7 interpreter, so integrations are delivered as Python modules.
+In order to be found by GOG Galaxy 2.0 an integration folder should be placed in [lookup directory](#deploy-location). Beside all the Python files, the integration folder must contain [manifest.json](#deploy-manifest) and all third-party dependencies. See an [exemplary structure](#deploy-structure-example).
 
-Install required packages:
-```bash
-pip install -r requirements.txt
+### Lookup directory
+
+<a name="deploy-location"></a>
+
+- Windows:
+
+    `%localappdata%\GOG.com\Galaxy\plugins\installed`
+
+- macOS:
+
+    `~/Library/Application Support/GOG.com/Galaxy/plugins/installed`
+
+### Logging
+<a href='https://docs.python.org/3.7/howto/logging.html'>Root logger</a> is already setup by GOG Galaxy to store rotated log files in:
+
+- Windows:
+
+    `%programdata%\GOG.com\Galaxy\logs`
+
+- macOS:
+
+    `/Users/Shared/GOG.com/Galaxy/Logs`
+
+Plugin logs are kept in `plugin-<platform>-<guid>.log`.
+When debugging, inspecting the other side of communication in the `GalaxyClient.log` can be helpful as well.
+
+### Manifest
+
+<a name="deploy-manifest"></a>
+Obligatory JSON file to be placed in an integration folder.
+
+```json
+{
+    "name": "Example plugin",
+    "platform": "test",
+    "guid": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
+    "version": "0.1",
+    "description": "Example plugin",
+    "author": "Name",
+    "email": "author@email.com",
+    "url": "https://github.com/user/galaxy-plugin-example",
+    "script": "plugin.py"
+}
 ```
 
-Run tests:
+| property      | description |
+|---------------|---|
+| `guid`        | custom Globally Unique Identifier |
+| `version`     | the same string as `version` in `Plugin` constructor |
+| `script`      | path of the entry point module, relative to the integration folder |
+
+### Dependencies
+
+All third-party packages (packages not included in the Python 3.7 standard library) should be deployed along with plugin files. Use the following command structure:
+
+```pip install DEP --target DIR --implementation cp --python-version 37```
+
+For example, a plugin that uses *requests* could have the following structure:
+
+<a name="deploy-structure-example"></a>
+
 ```bash
-pytest
-```
+installed
+└── my_integration
+    ├── galaxy
+    │   └── api
+    ├── requests
+    │   └── ...
+    ├── plugin.py
+    └── manifest.json
+```
+
+## Legal Notice
+
+By integrating or attempting to integrate any applications or content with or into GOG Galaxy 2.0 you represent that such application or content is your original creation (other than any software made available by GOG) and/or that you have all necessary rights to grant such applicable rights to the relevant community integration to GOG and to GOG Galaxy 2.0 end users for the purpose of use of such community integration and that such community integration comply with any third party license and other requirements including compliance with applicable laws.
