title: Branch descriptions in Git
body: <p>Is there a way in Git to have a 'description' for branches?</p>
  
  <p>While I try to use descriptive names, working for a while on a single branch sometimes dampens my memory of why I made some of the other topic branches. I try to use descriptive names for the branches, but I think a 'description' (short note about the purpose of the branch) would be nice. </p>
