This tutorial covers redirecting example.com to www.example.com when using Cloudflare, to do the opposite, please see Redirect www.example.com to example.com .
You should replace all instances of example.com in the screenshots with your domain.
Step 1, The DNS Record:
The first thing you will need is a DNS record for @, set to :orange:. This can point to any IP address as the redirection page rule will execute first. I would recommend pointing it to 192.0.2.1, a dummy IP.
