[Owncloud] an additional hint at the contribution guideline would be great

[Matthias Baumann]

Hi all,

using git on GitHub is nice, but the fist steps are clumsy.
I have found a great Howto,
http://gun.io/blog/how-to-github-fork-branch-and-pull-request/

I would be nice to have this link at the Contribution-Guideline-Site.

Thanks,
Matthias
