+## Ollama - Large Language Model Chat - Handler
+
+This handler "owns" the logic for accessing the ollama api, which runs the transformer model.
+
+> How to get started with a local chat bot see: [Run LLMs Locally using Ollama](https://marccodess.medium.com/run-llms-locally-using-ollama-8f04dd9b14f9)
+
+Assuming you are on the same network as the Ollama server you should configure it to be accessible to other machines on the network, however this is only required if you aren't running it from localhost relative to the bot.
+See: [How do I configure Ollama server?](https://github.com/ollama/ollama/blob/main/docs/faq.md#how-do-i-configure-ollama-server)

 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.
+
+*NOTE: you need to download the model from the Ollama ui, the model name which is preselected in the code is called ``gemma``.*
+
+## PM2 Setup
+- Install PM2 and configure it following their setup guide
+#### Lavalink
+* Download Lavalink 4.X.X (.jar)
+* Install Java 17
+
+If using Linux run following command to start Lavalink with PM2:
+``pm2 start "sudo java -Xmx1G -jar Lavalink.jar" --name Lavalink4.0.7``
+
+For me I have Lavalink.jar downloaded in ``/opt`` folder from Linux root. By running Lavalink using PM2, you can monitor it and manage it from a page in your browser instead of having to access the server terminal.
+#### Lunaris
+* Install dotnet
+
+Register the Lunaris bot with PM2:
+``pm2 start "dotnet Lunaris2.dll"``
+
