Welcome! We’re glad you made it to this page – we need everyone to get involved in order to transform our work and industry.

Each Action Guide contains: an overview of why the action is important, how to get started, and our favorite resources for going deeper. The guides are written by the CAT community. They are the result of many discussions, online searches, and work experiences. We will continue to edit and add to the guides as we gain more experience and understanding.

We are writing more guides right now. If you would like to make suggestions, help with writing or share a case study, join us in the #proj-action-guide channel.
