This is interesting to watch.

For a while there the project had been wiped out by someone who had mistakenly pushed to the master instead of pushing their own branch.

Now however it looks like they figured out how to reset the changes, as the original master branch is back again :)

Good job. Keep experimenting - and don't be afraid of messing up. As you can see it provides a good opportunity to figure out how to fix things.
