+# Cloudflare Pages
+
+Cloudflare offers the [Pages](https://pages.cloudflare.com/) service that can host Hugo blogs.
+It builds the site from a git repository and then hosts the site on Cloudflare's CDN.
+Follow their [Hugo deployment guide](https://developers.cloudflare.com/pages/framework-guides/deploy-a-hugo-site) to get started.

+The Rocker Loader™ feature offered by Cloudflare tries to speed up rendering of web pages with javascript, but it breaks the appearance switcher.
+It can also cause an annoying light/dark screen flash when browsing your site due to javascript loading in the wrong order.
+Fix this problem by disabling it:
+
+* Go to the [Cloudflare dashboard](https://dash.cloudflare.com)
+* Click on your domain name in the list
+* Click _Optimization_ in the _Speed_ section
+* Scroll down to _Rocket Loader™_ and disable it
+
+Hugo sites with the Congo theme still load very quickly even with this feature disabled.

 ## Shared hosting, VPS or private web server
 
 Using traditional web hosting, or deploying to your own web server, is as simple as building your Hugo site and transferring the files to your host.
