Meaningful commit messages

A short note, your git commit messages should start with "Fix" or "Add" instead of "Fixed" or "Added", which fits well in :

When merged/applied, this patch/commit will "<commit message>"

e.g. When merged, this commit will "fix the photo-viewer crash"

Learning GIT.

Follow http://rogerdudler.github.io/git-guide/ in order to get familiarized with the basics of git commands in the easiest manner.

In order to know more about version control and history of git you can go through
https://git-scm.com/book/en/v1/Getting-Started 

Git allows more than one person to safely work on the same project without interfering with each other's work.

Implement these commands by first creating an account on https://github.com/ and pushing any of your own projects.You can then play with commands, just make sure you are not messing up with the master branch. :D
