 ### I need to combine commits
 
-You need to do something called an interactive rebase.
+Let's suppose you are working in a branch that is/will become a pull-request against `master`. In the simplest case when all you want to do is to combine *all* commits into a single one and you don't care about commit timestamps, you can reset and recommit.
