+### Download the web UI bundle
+
+Once the server environment is working, you will need the latest files for the web UI. This is a Javascript bundle and
+you can download a pre-built copy from Github or compile your own.
+
+From [the `gh-pages` branch](https://github.com/ssube/onnx-web/tree/gh-pages), select the version matching your server
+and download all three files:
+
+- `bundle/main.js`
+- `config.json`
+- `index.html`
+
+Copy them into your local `api/gui` folder, making sure to keep the `main.js` bundle in the `bundle` subfolder.
+
+For example, for a v0.11 server, copy the files from https://github.com/ssube/onnx-web/tree/gh-pages/v0.11.0 into your
+local copy of https://github.com/ssube/onnx-web/tree/main/api/gui and
+https://github.com/ssube/onnx-web/tree/main/api/gui/bundle.
