 You can now start building your Generative AI application powered by the Docker Model Runner.
 
 If you want to try an existing GenAI application, follow these instructions.

 You can now interact with your own GenAI app, powered by a local model. Try a few prompts and notice how fast the responses are — all running on your machine with Docker.
 
+### Use Model Runner in GitHub Actions
+
+Here is an example on how to use Model Runner as part of a GitHub workflow.
+The example installs Model Runner, tests the installation, pulls and runs a model,
+interacts with the model via the API and finally deletes the model.
