 2. Launch ComfyUI by running `python main.py`
 
+## Running with Docker
+
+Start by installing Docker, Docker Compose, and the NVIDIA Container Toolkit on
+your host. Next, edit `compose.yaml` and update the `UID` and `GID` variables to
+match your user. Additional fields are documented in the file for further
+customization.
+
+Once ready, build and run the image locally:
+
+```shell
+# (Re)build the Docker image. Run this before the first start, after updating
+# ComfyUI, or after changing any build arguments in `compose.yaml`.
+docker compose build
+# Start ComfyUI. This reuses the most recently built image.
+docker compose up
+```
+
+To stop and remove the container along with its volumes, run:
