cnrailwiki.miraheze.org: <You should have your miraheze.org subdomain. Please list that here, so we can know what URL you currently have. If your wiki is not created yet, you can make a task first and click "Edit Task" to change it later.>
cnrailwiki.org: <Replace this with your desired wiki domain.>
Do you want Let's Encrypt: <Yes>
By the way, I used Cloudflare for both registering the new domain cnrailwiki.org, and run CDN services. How can I point this domain to the original domain cnrailwiki.miraheze.org? Would be glad if you could help.
