 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 performing another checkout.
 
 If you want to create a new branch to retain commits you create, you may
 do so (now or later) by using -b with the checkout command again. Example:
 
   git checkout -b <new-branch-name>
