title: Replacing Everything in a GitHub repo that is linked to a custom URL
body: <p>So, I have a repo called DSU on my computer that I push to GitHub, and I have linked that repo to my custom domain, you know, mydomain.org.</p>
  <p>Now I have done a complete overhaul of the site in another repo, REALLY on my computer.  I plan to do this: erase everything in the repo DSU, copy all of REALLY to DSU, and then push to GitHub like normal.</p>
  <p>But boy and I afraid that weird things will happen.</p>
  <p>Or is there a better way to do that?  What I really want to avoid is going through all the steps to link a GitHun repo to a custom URL, because that was hard for me.</p>
  <p>But, I figure if the repo DSU on GitHub is already pointed to mydomain.org, then I can change whatever I put in that repo, and it will still be viewable at mydomain.org.</p>
  <p>If I delete the repo on GitHub, and then create a new repo with exactly the same name, will it still link to mydomain.org?</p>
