# Utility AI GDExtension Tutorials

The goal of these tutorials is to help you learn how to use the Utility AI GDExtension nodes.


### Installation and setup

|Tutorial|Description|
|--|--|
|[How to install Utility AI GDExtension](How_to_install_Utility_AI_GDExtension.md)|Installation steps for Utility AI GDExtension using the Godot Asset Library or manually.|
|[Using the AIPerformanceMonitor](Using_the_AIPerformanceMonitor.md)|How to setup the AI Performance monitor to measure the performance of the AI you've built for your game.|
|[Using the NodeQuerySystem performance monitors](Using_the_NodeQuerySystemMonitor.md)|How to setup the NodeQuerySystem Performance monitors to measure the performance of NQS queries.|

### Getting started

These getting started tutorials create the same AI using AI Agent Behaviours, a Behaviour Tree and a State Tree. A similar behaviour is created also using the Node Query System. The AI will follow the mouse cursor but keep a minimum distance to it. The final getting started tutorial gives basic knowledge about debugging.
