Make sure they create their repositories in separate directories
This time it was better than last time, but I still saw quit some students ending up with nested Git repositories.
One of the things we should fix is in the Git Basics slides which contain the following instructinos:
cd ~/projects
git init
Instead, I think we should first let them create a project subdirectory and initialize a repository there.
There might be other places where we could make the correct structure a bit more explicit.
