One of my goals is to learn and master Git and GitHub this year and I have been searching for some good tutorials and courses to start with. The Internet is full of git tutorials and a simple Google search will leave you thousands of tutorials but the big question mark is where do you start?

I personally like learning from a book or an online course before moving to blog posts as they were often well structured.
