+## How to change entry point name
+1. Create ``pyg2o.json`` in your root server folder
+2. Place this content in it and change entry point name
+```json
+{
+    "entry": "your_entry_name"
+}
+```

+## How to add additional packages folder (use virtual environment)
+You can create ``.pth`` file in your root server folder and it will be added to your ``sys.path`` before entry point
