Hi Jane,
Welcome to the Git community and welcome to Outreachy!
It's great to see your introduction here. Going through "My First Contribution" is a wonderful way to start. Don't worry if the codebase feels new or overwhelming at first—take it step by step, and you will get the hang of it very quickly.
Wishing you the best of luck with your first microproject and your contribution journey!
Kind regards,
Keryle
