Hey @LeoKirasic,

Thank you for your appreciation. I understand your concern, I won't review any issues/pull requests until I'm a part of TOP.

Let me know if I can help with anything else.

@rafaover thank you for taking the time to put this PR together!

Unfortunately, I also don't believe that these resources are appropriate for the git basics lesson, and I don't really see the other cheatsheets adding much value to the intermediate git lesson since the Atlassian cheatsheet is already linked there and covers most of the same material.

For those reasons, I'm going to close this PR, but thank you again for taking the time to try and contribute!
