I am wanting to use a custom URL for this github website, but I ran into issues when I tried. The repo is below if you want to view my files. I had to do a 'git reset --hard "commit" ' to get it working again!
I dont know if I need to change my base URL too because none of the css worked, and no href links to other pages on the server worked either. Then I was getting build errors on github with no details as to why.
Steps I took:
1) I have a domain with godaddy
2) Then I went to github and changed the Custom url to the domain i have on github.
3) Then github created a cname file by its self with my url in it
4) I went to godaddy and pointed to the servers provided by github.
5) It display my html files, but no href links work, and CSS is not working. I think it has something to do with the base url or something...
In _config.yml change :
baseurl: ""
url: "http://yourcustome-domain-url.com"
And add a CNAME because github doesn't create it for you.
