6You are in 'detached HEAD' state. You can look around, make experimental

7changes and commit them, and you can discard any commits you make in this

8state without impacting any branches by switching back to a branch.

9

10If you want to create a new branch to retain commits you create, you may

11do so (now or later) by using -c with the switch command. Example:

12

13 git switch -c <new-branch-name>

14

15Or undo this operation with:

16

17 git switch -

18

19Turn off this advice by setting config variable advice.detachedHead to false
