Oh, that annoyed me more than it should. Yes, it's quite easy to make your custom domain point to your GitHub Pages project, but from the confusing GitHub documentation (too much freaking information) to the annoying first-page Google results, took me a while for everything to work properly.
- you already have a custom domain (mine is drugowick.dev)
- you already have a GitHub Pages project (if you don't...)
... here are the 3 simple steps to use your GitHub Pages project with your domain:
On your GitHub Pages repository settings (
https://github.com/<your-username>/<your-username>.github.io/settings) in the
Custom domainfield, put your custom domain including the www in the beginning, like so:
Check the box
Enforce HTTPS(you may have to wait a little for this option to be available).
- A set of
Arecords pointing to GitHub's IPs. Here you can find the updated IP addresses that should be used.
CNAMErecord pointing to
wwwon the Name field.
Wait a little bit again for everything to work. It will work!
Well... it works for me! =)
