[chef] Cookbook contribution [rsyslog]?

[Denis Barishev < >]

Hello folks!

Could anyone, please, explain or give links to information where it is 
explained how to contribute to community cookbooks.
Recently I modified rsyslog cookbook as I found it not versatile enough. 
So I want to commit my changes to the community cookbook. There's that 
repository where I could push my changes? What is the procedure of 
changes approval?

Regards,
Denis
