We'd love you to contribute! We do have a couple of processes to follow though depending on the "phase" of the module you're using:
Draft phase: Please submit pull requests to the appropriate module "specification" file and indicate your suggested changes. Feel free to review other requests too. Requests will be merged by a SilverLeague community member once approved.
Development and active support phase: Ideas, proposals and contributions are readily accepted in the form of issues or pull requests on the appropriate SilverLeague repository. Pull requests can be merged by one of the module's maintainers (see the module's readme for who they are).
