Datt is an open-source project, application, protocol, community, and business that accepts valuable contributions from anyone. Most of our code, documents and media are in the main datt repo (probably where you are viewing this document right now), so that is probably where you will want to make your contribution. Before making a contribution, you may want to check our known issues to see if someone else is already working on your issue. If not, fork our repository, make your changes, and issue a pull request to the appropriate repo. Someone with commit access (probably Ryan X. Charles) will review your pull request and give feedback, and accept it if it enhanes the project.
