+# ComfyUI
+
+## Overview
+
+Node-based interface for AI image generation workflows.
+
+## Project Details
+
+-   **Project Repository:** [GitHub](https://github.com/comfyanonymous/ComfyUI)
+-   **Container Image:** [yanwk/comfyui-boot](https://hub.docker.com/r/yanwk/comfyui-boot)
+-   **Documentation:** [comfy.org](https://docs.comfy.org/)
+-   **Reverse Proxy Port:** `8188`
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:8188 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    COMFYUI_IMAGE – pick the tag matching your CUDA version (cu124-slim, cu121, etc.)
+
+## Volume Notes
+
+    /root – models, custom nodes, outputs, and settings
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name comfyui \
+  --gpus all \
+  -p 8188:8188 \
+  -v /data/comfyui:/root \
+  yanwk/comfyui-boot:cu124-slim
+```
+
+## Additional Notes / Gotchas
+
+ComfyUI has no official image; yanwk/comfyui-boot is the most maintained community image.
+GPU access is required for practical use — install the NVIDIA Container Toolkit and add a `gpus` / deploy reservation to the compose file (not included here since it depends on host setup).
+Models are large; expect 20+ GB in the /root volume.
