-Now you make some new commits on your ``cool-feature`` branch, let's call them
-A, B, C. Maybe your changes take a while, or you come back to them after a

-
-          A---B---C cool-feature
-         /
-    D---E---F---G main

-At this stage you consider merging ``main`` into your feature branch, and you

-history will get messy. Most of the time you can just ask for a review, and not
-worry that ``main`` has got a little ahead.  But sometimes, the changes in
-``main`` might affect your changes, and you need to harmonize them.  In this
-situation you may prefer to do a rebase.
-
-``rebase`` takes your changes (A, B, C) and replays them as if they had been
-made to the current state of ``main``.  In other words, in this case, it takes
-the changes represented by A, B, C and replays them on top of G. After the
-rebase, your history will look like this:
