Commitment Issues

Description

I accidentally wrote the flag down. Good thing I deleted it! You download the challenge files here:

Hints

  1. Version control can help you recover files if you change or lose them!
  2. Read the chapter on Git from the picoPrimer PicoPrimer.
  3. You can 'checkout' commits to see the files inside them.
