How to use a custom domain

I know of those docs (https://docs.railway.app/deploy/exposing-your-app), but I've never done something like this before, so I'm not sure what to do. Am I required to host my domain somewhere else and then somehow link it to railway?

you add a CNAME record pointing to the railway subdomain

I'm sorry, but what does that mean and how do I do it? Also, what do you mean subdomain? I'd like to use a "regular" domain such as abcdefg.com.

No Can I do this through railway or do I have to go somewhere else and then link it?

you have to buy a domain through a domain registrar you can find a good price using https://tld-list.com and for actually buying one i recommend namecheap or porkbun or cloudflare domains

What do I set those fields to? My initial theory is: - Leave host blank - Answer: The Railway URL?

yep but remove the https:// from the beginning

Do you have an idea what to do about this error? Any idea how "ALIAS - CNAME flattening record" differs from the option I tried?

yeah you should use cname flattening

Seems to have worked, thanks a lot! 🙂
