There are several ways to contribute or modify GSD data: (1) via the website, and (2) via pull requests, and (3) by filing issues For small updates, we recommend using the website. For larger bulk additions, we recommend a pull request (and a heads up).
Contributing via the Website
This is currently partially implemented, the edit button will generate an issue with the changes but it is not yet automatically handled.
Contributing via Pull Requests
The GSD database uses a standard fork and PR request model for making contributions.
