+AI Gallery
+====================
+
+
+AI Gallery is a collection of ready-to-run recipes for popular AI frameworks and AI models.
+It provides a simple way to **package**, **share**, and **run** AI projects using the simple interface of SkyPilot.
+
+You can directly execute the SkyPilot YAMLs on your own infrastructure, such as :ref:`cloud VMs <installation>` or :ref:`Kubernetes <kubernetes-overview>`.

+Contents
+--------
+
+.. Relative paths are not supported in README.md. Instead, we should use GitHub
+.. URLs for the references to the files.

+
+Adding an Example to the Gallery
+--------------------------------
+We welcome contributions from the community. If you would like to contribute, please follow the guidelines below.
+
+1. Fork the `SkyPilot repository <https://github.com/skypilot-org/skypilot>`__ on GitHub.
+2. Create a new folder for your own framework, LLM model, or tutorial under `llm/ <https://github.com/skypilot-org/skypilot/tree/master/llm>`__.
+3. Add a README.md, a SkyPilot YAML, and other necessary files to run the AI project.
+4. Create a soft link in `docs/source/_gallery_original <https://github.com/skypilot-org/skypilot/blob/master/docs/source/_gallery_original>`__ to the README file in one of the subfolders (frameworks, llms, tutorials), e.g., :code:`cd docs/source/_gallery_original/llms; ln -s ../../llm/mixtral/README.md mixtral.md`.
+5. Add the file path to the ``toctree`` above on this page.
+6. Create a pull request to the `SkyPilot repository <https://github.com/skypilot-org/skypilot/compare>`__.
+
+If you have any questions, please feel free to ask in the `SkyPilot Slack <https://slack.skypilot.co>`__.
