## Built-in node documentation

Documentation for ComfyUI's built-in nodes is maintained in the [embedded-docs repository](https://github.com/Comfy-Org/embedded-docs).

**Contributing to built-in node docs:**

* Users can contribute improvements and additions to built-in node documentation
* Submit pull requests to the [embedded-docs repository](https://github.com/Comfy-Org/embedded-docs)
