command—you use it to begin tracking new files, to stage files, and to do other things like marking merge-conflicted files as resolved. It may be helpful to think of it more as “add precisely this content ASCII graph showing your branch and merge history: $ git log --pretty=format:"%h %s" --graph * 2d3acf9 Ignore errors from SIGCHLD on trap * 5e3ee11 Merge branch 'master' of https://github e1193f8 Support for heads with slashes in them |/ * d6016bc Require time for xmlschema * 11d191e Merge branch 'defunkt' into local This type of output will become more interesting as we go through
