 Basic implementation:
 
 ```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
 
 class PluginExample(Plugin):
+    def __init__(self, reader, writer, token):
+        super().__init__(
+            Platform.Generic, # Choose platform from available list
+            "0.1", # Version
+            reader,
+            writer,
+            token
+        )
+
     # implement methods
     async def authenticate(self, stored_credentials=None):
         pass
 
+def main():
+    create_and_run_plugin(PluginExample, sys.argv)
+
 # run plugin event loop
 if __name__ == "__main__":
-    asyncio.run(PluginExample().run())
+    main()
+```

+Plugin should be deployed with manifest:
+```json
