add contributing file in the root dir

How about adding a CONTRIBUTING.md file?

Maybe it is better to put the contribution/documentation/overview.rst document as CONTRUTING file.

Linking to the relevant contribution section of the documentation on symfony.com was the decision made for symfony itself.

This is not enough anymore. the master branch is now for 2.2 and 2.1 also has its branch

[wouterj]

@richardmiller well, maybe we need to change that decision. I think most of the contributors, unless you are a core contributor, don't read the overview file. We get lots of errors and unneeded comments in PR's because they didn't read the file.

I think more people will read it if you place it in the README/CONTRIBUTORS file.

I really like this idea, but I also agree that this should be very simple - just like: https://github.com/symfony/symfony/blob/master/CONTRIBUTING.md

So let's simplify this a bit. But I love it - I think that people do tend to know to look for a CONTRIBUTING file and I also like that the docs follow the example set by the core code.

Thanks!

Something like this:

We love contributors! If you'd like to contribute to the Symfony documentation, please read the Contributing to the Documentation section.

Hey guys!

Yep, I like what we have here - I've merged in the PR and just removed the top paragraph.

Thanks!
