How we got here

We are licensed developers with access to Valve's source code repositories. We received permission to use the code to develop this project. To contribute to Portal 2: Community Edition's code, you would be required to be under Valve NDA and have access to the source code yourself.

This is the entire purpose of this mod. Only very few people are able to alter Portal 2's source code, so we want to make use of our position by implementing as many features as possible and make them available to everyone.
