+## Page search
+
+The spec uses [Pagefind](https://pagefind.app/) to provide a page search widget. To test this locally, you'll need to generate the
+search index _after_ building the static site.
+
+```
+hugo build && npm run pagefind -- --site public && hugo serve
+```
+
+Note that while `hugo serve` supports hot reloading, changes made to the site content won't reflect in the search index without
+rebuilding it.

 ## Building the specification
 
 If for some reason you're not a CI/CD system and want to render a static version of the spec for yourself, follow the above
