Customer Request: Improve initial commit guide to also help users work out how to add all the other files and commit.

Customer request:

Every time when I need to add a repository to Bitbucket - once the repository is created, > we follow the instructions to submit an application from scratch.

This is fine for adding the contributors file. I then searched the internet to work out how > to add all the other files and then commit them.

Please just add these commands to the guide to help me and others save time and
effort searching the internet.
i.e. add
git commit -m 'Initial commit'
$ git push origin master

The other point is that in the Git CMD window the single quote has to be replaced with a > double quote to work.
