+## Generated functions
+
+This plugin works by generating three Netlify functions that handle requests that haven't been pre-rendered. These are
+`___netlify-handler` (for SSR and API routes), `___netlify-odb-handler` (for ISR and fallback routes), and `_ipx` (for
+images). You can see the requests for these in [the function logs](https://docs.netlify.com/functions/logs/). For ISR
+and fallback routes you will not see any requests that are served from the edge cache, just actual rendering requests.
+These are all internal functions, so you won't find them in your site's own functions directory.
