On 2020-06-22, we renamed the master branch to main.

This should mean very little, but if you have existing clones, you'll need to update the branch references, like so:

1. Fetch the latest branches from the remote:
   $ git fetch --all
2. Update the upstream remote's HEAD
   $ git remote set-head origin -a
3. Switch your local branch to track the new remote
   $ git branch --set-upstream-to origin/main
4. Rename your branch locally
   $ git branch -m master main

The master branch was fully deleted on 2020-07-28. If you get an error on pull on an old clone, that's why. The commands above should still work, though.
