 +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
 +
 +HEAD is now at d4a8ab1... added initial text to file 1
