Could you please introduce resources for learning more about Git and GitHub?

Question

Could you please introduce a good yet concise source/website to learn more about Git and Github?

Answer 1

You can start with the following cheat sheets to review what are available in Git. The first two cheat sheets are from GitHub (click to download the pdf version), and the last two cheat sheets are taken from git-tower.com. If you are looking a complete step by step course from the beginning, you can also take a look at Learning Git and GitHub from Lynda.com.
