 ### How to run Nextcloud behind a Cloudflare Tunnel?
 Although it does not seems like it is the case but from AIO perspective a Cloudflare Tunnel works like a reverse proxy. So please follow the [reverse proxy documentation](./reverse-proxy.md) where is documented how to make it run behind a Cloudflare Tunnel. However please see the [caveats](https://github.com/nextcloud/all-in-one#notes-on-cloudflare-proxytunnel) before proceeding.
