Provide hints or an explanation how to solve a level

[UweSauter]

When struggling with a level it would be nice to have a button that would provide a hint or two before giving a set of instructions on how to complete a level. This could also used to present the concept of each level in more detail.

Love the app idea, pretty cool :)

Agreed with providing hints - I'm about 1/3 of the way through and one or two places I had to go google documentation.

Some example questions I had to research outside of app:

1. Is there an equivalent of HEAD^ or HEAD~2 that allows you to move forward in the timeline. Answer - no, since when moving forward, you might actually have two separate commits branching out from a starting point. You can't know which one to move forward to without explicitly specifying the commit hash you want.

2. What happens when you delete a branch on a parallel commit? Does that "stray" commit just linger there? Answer (I think?) - git gc or garbage collection, can clean up "orphaned" commits that aren't part of a branch, you can run it manually, and (maybe? not sure) this "periodically" happens automatically.

Hints would be really awesome. Or even a solution somewhere I could review. I'm stuck on rebasing, and can't figure out what to do to finish, or if I'm on the complete wrong track.
