Become a Contributor
We are SO excited you want to join us and help build the next generation of Web development tools! The first thing we ask is that you have a Contributor License Agreement (CLA) in place before submitting code.
Most forms of contribution aside from providing support to other users requires that you sign and submit a Contributors License Agreement (or "CLA" for short) with the Dojo Foundation. Sending in a CLA is a one-time thing, and once it's done, you're in the clear to start contributing to all Dojo Foundation projects!
There are two versions of the agreement:
You're working on a Dojo Foundation project in your spare time, or can clearly claim ownership of copyright in what you'll be submitting
Have your corporate lawyer review and submit this if your company is going to be contributing to Foundation projects
In summary, the CLA asserts that when you donate fixes or documentation, you both own the code that you're submitting and that the Dojo Foundation can in turn license that code to other people.
