Useful Git Tutorial

I found this very useful Git link: http://www-cs-students.stanford.edu/~blynn/gitmagic/. I really learnt a lot about it. Another useful link is: http://progit.org/book/. Here are a few things I learnt from these links:

• "Snapshots, Not Differences" git does not store differences but new versions of files which changed and links to the unchanged one.
• reordering of commits Using Git, you can commit code to your repository and then reorganize the order of your commits. This makes it much more simpler to group changes in a meaningful way.
• branching is easy
