 ## OpenAI Api key
 To get the OpenAI api key you need to create a account at [https://platform.openai.com](https://platform.openai.com) and create a key in the user settings. That key has to be added in the [application.properties](https://github.com/Angular2Guy/AIDocumentLibraryChat/blob/master/backend/src/main/resources/application.properties) at the key: 'spring.ai.openai.api-key'.
 As alternative it can be provided as the environment variable 'OPEN-API-KEY'.
 
+## Ollama setup
+[Ollama](https://ollama.ai/) can run the AI model locally. The file [runOllama.sh](https://github.com/Angular2Guy/AIDocumentLibraryChat/blob/master/runOllama.sh) has the commands to run it as Docker container. The application needs to be build with the 'useOllama=true' Gradle build property to include the dependencies. The application needs to be started with the 'ollama' profile to switch on the configs/features to use Ollama based models. Ollama has support for GPU acceleration.
