+### Deploy to your dev project and version
+
+This will run `npm run build`, copy the `app.yaml` into the `dist/` directory
+and deploy the app from there at the specified project and version ID.
+
+```shell
+npm run deploy --project=my-project --app_version=my-version-id
+```
+
+Once deployed, the version will be available to test at the specified project
+and version, e.g.:
+https://my-version-id-dot-my-project.appspot.com
+
+### Deploy to beta (for GeoViz maintainers)
+
+```shell
+npm run deploy:beta
+```
+Once deployed, the version will be available to test here:
+https://beta-dot-bigquerygeoviz.appspot.com
+
+### Deploy to a (prod) version (for GeoViz maintainers)
+
+```shell
+npm run deploy:prod --app_version=my-version-id
+```
+
+Once deployed, the version will be available to test at the specified version:
+https://my-version-id-dot-bigquerygeoviz.appspot.com
+
+To prevent accidentally pushing it live, the version will not be set as default.
+To make it the default version, you will need to
+[migrate it directly on the Cloud Console](https://cloud.google.com/appengine/docs/legacy/standard/python/migrating-traffic).
