+## Publish a preview to GitHub Pages
+
+We sometimes publish to GitHub Pages for in-progress previews. The recommended
+flow for publishing is:
+
+- Install the `ghp-import` tool by running `pip install ghp-import` (or `pipx install ghp-import`, using [pipx][pipx]).
+- In the root, run `tools/generate-preview.sh`
+
+[pipx]: https://pipx.pypa.io/stable/#install-pipx
