Git Detached HEAD
A detached HEAD means HEAD points straight to a commit, not to a branch. You get one when you check out a commit hash or a tag.
New commits you make are not on any branch, so switch back to a branch, or create one, before you go on.
Check out an older commit
git checkout HEAD~2
Note: switching to 'HEAD~2'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
