We've only scratched the very surface of Git: it's a really powerful and some-
times quite complicated tool. Whole topics are devoted just to Git (including
Pragmatic Version Control Using Git [Swi08]
and
Pragmatic Guide to Git [Swi10]
).
But hopefully this is enough to get you started.
Next Up
Git is a powerful tool, not just because it gives you a project-wide “undo
button,” but because it allows you to experiment
with confidence
. You don't
have to be afraid that you'll screw everything up. When you
do
screw every-
thing up, Git lets you “unscrew” it back to the point where it all worked. With
branches, you can even try a couple of different approaches in code. Not sure
if you should use an array or a hash? Not sure if the listener should be in a
separate class? You can use branches to try things out.
With that freedom in hand, you're ready for the final step.
