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.
