How can I merge two branches?

Branching lets you create parallel universes; merging is how you bring them back together. When you merge one branch (call it the source) into another (call it the destination), Git incorporates the changes made to the source branch into the destination branch. If those changes don't overlap, the result is a new commit in the destination branch that includes everything from the source branch (the next exercises describe what happens if there are conflicts).

To merge two branches, you run git merge source destination (without .. between the two branch names). Git automatically opens an editor so that you can write a log message for the merge; you can either keep its default message or fill in something more informative.
