Head

You'll see a big scary word in the Git world called HEAD. Branches are references to commits, and HEAD is a reference to the branch you're currently on. All this to say, in Grug speak:

HEAD mean where me at now

For example, you should be on the main branch of your local clone of your fork of the official MegaCorp™ repo. Which means, HEAD is pointing to the main branch. Like all things in .git's internals, HEAD is just stored in a file.

Assignment

Manually check and see what HEAD is pointing to from the root of your repo:

cat .git/HEAD

If you haven't already, close the PR without merging and delete the add_contrib branch from your local repo.

Run and submit the CLI tests.

Tip

To delete a branch locally while in a different branch:

git branch -D branch_name
