 We now need to synchronize between the game running in Godot and the neural network being trained in Python. Godot RL agents provides a node that does just that. Open the train.tscn scene, right click on the root node, and click “Add child node”. Then, search for “sync” and add a Godot RL Agents Sync node. This node handles the communication between Python and Godot over TCP.

 We have only scratched the surface of what can be achieved with Godot RL Agents, the library includes custom sensors and cameras to enrich the information available to the agent. Take a look at the [examples](https://github.com/edbeeching/godot_rl_agents_examples) to find out more!
 
+For the ability to export the trained model to .onnx so that you can run inference directly from Godot without the Python server, and other useful training options, take a look at the [advanced SB3 tutorial](https://github.com/edbeeching/godot_rl_agents/blob/main/docs/ADV_STABLE_BASELINES_3.md).
