 5. Make sure you got docker installed. And run the file ``start-services.sh``, make sure you got git-bash installed.
 6. Now you can start the project and run the application.
 
+## LLM
+Lunaris supports AI chat using a large language model, this is done by hosting the LLM locally, in this case Docker will set it up for you when you run the start-services script.
+
+The LLM is run using Ollama see more about Ollama [here](https://ollama.com/). Running LLM locally requires much resources from your system, minimum requirements is at least 8GB of ram. If your don't have enought ram, select a LLM model in the [appsettings file](https://github.com/Myxelium/Lunaris2.0/blob/master/Bot/appsettings.json#L15) that requires less of your system.

 ## Usage
 
 - `/play <song>`: Plays the specified song in the voice channel you're currently in.
