  Clone or unpack the HEISS-UI repo (github.com/tristmeister/HEISS-UI), start it with `npm start` from its folder, and confirm the studio opens in the browser. Then pick <model name> from the model menu, enter the prompt <prompt text>, and report the path of the rendered image in the gallery. Verify that the models list is populated, which means ComfyUI is connected.

Quick start with HEISS UI

1. Check you have what it needs: A ComfyUI install that is running, such as ComfyUI Desktop, or reachable at a known address; A Windows, macOS (Apple Silicon) or Linux computer, or Node.js 20.9+ if you install from source; Enough disk space for the model files you choose to download.
2. Open tristmeister/HEISS-UI on GitHub and read the README and license.
3. Download the zip for your system from the latest release on the HEISS UI GitHub page.
4. Unpack it and double-click Start HEISS UI (.bat on Windows, .command on macOS, .desktop on Linux), or run npm start in the folder.
5. Make sure ComfyUI is running; ComfyUI Desktop connects on its own, and other addresses are set under Settings › Connection.
6. Pick one of the 30 built-in model families and press Get all if it reports missing parts.

These steps come from our top use case, Generate images from a prompt without the node graph, which also has a copy-paste agent prompt.
