## Getting the framework ## Getting the framework
This repository contains just the framework to make it easy for you to install it. This repository contains the framework and some demos for learning purposes.
You should also check out the [Steering AI Framework Demos](https://github.com/GDQuest/godot-steering-ai-framework-demos) repository! It contains many demos to learn to use the framework and see what you can achieve with it. If you want just the framework with nothing else to get in the way or to create a Git submodule, use the [Godot Steering AI Framework Submodules](https://github.com/GDQuest/godot-steering-ai-framework-submodule) repository.
