title = Branching out
cards = checkout commit-auto merge reset-hard
[description]
You can use these little blue labels to give names to different timelines! This makes it easier to remember what happened where.
One of your colleagues messed up here - can you help reordering the branches correctly using the "reset" card?
When you do commits or merges while you're on a branch, the branch will grow with you. Try that while you eat that donut.
Finally, merge all timelines together, in a way so that the "main" branch points to the result. That's base reality!

You do not have coffee.

Nice! It's often convenient to stay on branches most of the time!
