docs(readme): document baked-in SageAttention 2.2 and default enable via --use-sage-attention
Update README to reflect that SageAttention 2.2/2++ is compiled into the
image at build time and enabled automatically on launch using
--use-sage-attention. Clarifies NVIDIA GPU setup expectations and that no
extra steps are required to activate SageAttention in container runs.

Changes:
- Features: add “SageAttention 2.2 baked in” and “Auto-enabled at launch”.
- Getting Started: note that SageAttention is compiled during docker build
  and requires no manual install.
- Docker Compose: confirm the image launches with SageAttention enabled by default.
- Usage: add a SageAttention subsection with startup log verification notes.
- General cleanup and wording to align with current image behavior.

No functional code changes; documentation only.

## About
This repository automates the creation of Docker images for [ComfyUI](https://github.com/comfyanonymous/ComfyUI), a powerful and modular stable diffusion GUI and backend.
It syncs with the upstream ComfyUI repository, builds a Docker image on new releases, and pushes it to GitHub Container Registry (GHCR).
I created this repo for myself as a simple way to stay up to date with the latest ComfyUI versions while having an easy-to-use Docker image.
It's particularly suited for setups with **NVIDIA GPUs**, leveraging CUDA for accelerated performance.
### Built With
- [Docker](https://www.docker.com/)
- [GitHub Actions](https://github.com/features/actions) for automation
- [PyTorch](https://pytorch.org/) with CUDA support
- Based on Python 3.12 slim image
---
## Features
- **Automated Sync & Build**: Daily checks for upstream releases, auto-merges changes, and builds/pushes Docker images.
- **NVIDIA GPU Ready**: Pre-configured with CUDA-enabled PyTorch for seamless GPU acceleration.
- **Non-Root Runtime**: Runs as a non-root user for better security.
- **Pre-Installed Manager**: Includes ComfyUI-Manager for easy node/extensions management.
- **SageAttention 2.2 baked in**: The image compiles SageAttention 2.2/2++ from the upstream repository during docker build, ensuring the latest kernels for modern NVIDIA GPUs are included by default.
- **Auto-enabled at launch**: ComfyUI is started with the `--use-sage-attention` flag so SageAttention is activated automatically on startup (no extra steps required).
---
## Getting Started
### Prerequisites
- **Docker**: Installed on your host (e.g., Docker Desktop or Engine).
- **NVIDIA GPU**: For GPU support (ensure NVIDIA drivers and CUDA are installed on the host).
- **NVIDIA Container Toolkit**: For GPU passthrough in Docker (install via the official guide).
### Pulling the Image
The latest image is available on GHCR:
```bash
docker pull ghcr.io/clsferguson/comfyui-docker:latest
```
For a specific version (synced with upstream tags, starting at 0.3.57):
```bash
docker pull ghcr.io/clsferguson/comfyui-docker:vX.Y.Z
```
### Docker Compose
For easier management, use this `docker-compose.yml`:
```yaml
services:
comfyui:
image: ghcr.io/clsferguson/comfyui-docker:latest
container_name: ComfyUI
runtime: nvidia
restart: unless-stopped
ports:
- 8188:8188
environment:
- TZ=America/Edmonton
- PUID=1000
- GUID=1000
gpus: all
volumes:
- comfyui_data:/app/ComfyUI/user/default
- comfyui_nodes:/app/ComfyUI/custom_nodes
- /mnt/comfyui/models:/app/ComfyUI/models
- /mnt/comfyui/input:/app/ComfyUI/input
- /mnt/comfyui/output:/app/ComfyUI/output
```
Run with `docker compose up -d`.
---
## Usage
### Basic Usage
Access ComfyUI at `http://localhost:8188` after starting the container using Docker Compose.
### SageAttention
- SageAttention 2.2 is built into the image and enabled automatically on startup via `--use-sage-attention`.
- To verify, check the container logs on startup; ComfyUI will print a line indicating SageAttention is active.
### Environment Variables
- Set via `.env` file or `-e` flags in `docker compose` or `docker run`.
