Missions: Using Git
Somebody out there tried to write a "Hello, world!" program, but they wrote it as "Goodbye, world!". What a mess! Luckily, you can step in and submit a patch. I bet the maintainer would gladly accept it too!
The intended audience are new contributors to open source. If you can edit a text file and use a terminal, you can complete this mission.
What you'll learn
You will learn how to clone a git repository, make a commit, submit a patch, and rebase your work onto the new version provided by the maintainer.
If you were logged in, you could create a repository that you could use to do these missions.
