28 You are in ‘detached HEAD‘ state. You can look around, make experimental
29 changes and commit them, and you can discard any commits you make in this
30 state without impacting any branches by performing another checkout.
31 
32 If you want to create a new branch to retain commits you create, you may
33 do so (now or later) by using -b with the checkout command again. Example:
34 
35   git checkout -b new_branch_name
36 
37 HEAD is now at e24385f... merge modify_election_datanode_algorithm
