You are welcome to contribute to PSL by making a technical contribution to PSL infrastructure like the website and Catalog-Builder, adding a model to the library, or contributing to one of the models already in the library.
When you feel that you have made a valuable contribution, please add it to RELEASES.md. If you think PSL users should know about it, add it to NEWS.md. If your name is not already in contributors.md, add it.
To submit a public policy simulation project to PSL, please bring your model or data preparation routine into compliance with PSL Criteria and then open a pull request to PSL adding your model to the PSL Catalog Register. The PSL project will then review your PR for public policy relevance and conformance to the PSL Criteria. If you have a question about the process or are unsure of your project's relevance to PSL, please open an issue.
If you are interested in becoming a contributor to the PSL community, we welcome you to join one of our community calls. Please see the PSL events page for a calendar of upcoming meetings. General community calls and project-specific calls are held on a regular basis and are open to the public.
