 Thank you for looking into contributing to GEOS-Chem! GEOS-Chem is a grass-roots model that relies on contributions from community members like you. Whether you're new to GEOS-Chem or a longtime user, you're a valued member of the community, and we want you to feel empowered to contribute.
 
-Updates to the GEOS-Chem model benefit both you and the [entire GEOS-Chem community](https://geoschem.github.io/geos-chem-people-projects-map/).  You benefit through [coauthorship and citations](https://geos-chem.seas.harvard.edu/geos-new-developments).  Priority development needs are identified at GEOS-Chem users' meetings with updates between meetings based on [GEOS-Chem Steering Committee (GCSC)](https://geos-chem.seas.harvard.edu/geos-steering-cmte) input through [Working Groups](https://geos-chem.seas.harvard.edu/geos-working-groups).

 ## We use GitHub and ReadTheDocs
 We use GitHub to host the GCHP source code, to track issues, user questions, and feature requests, and to accept pull requests: [https://github.com/geoschem/GCHP](https://github.com/geoschem/GCHP). Please help out as you can in response to issues and user questions.

 ## What type of support can I expect?
-We will be happy to assist you in resolving bugs and technical issues that arise when compiling or running GEOS-Chem.  User support and outreach is an important part of our  mission to support the [International GEOS-Chem User Community](https://geoschem.github.io/geos-chem-people-projects-map/).

 Even though we can assist in several ways, we cannot possibly do everything.  We rely on GEOS-Chem users being resourceful and willing to try to resolve problems on their own to the greatest extent possible.
 
-If you have a science question rather than a technical question, you should contact the relevant [GEOS-Chem Working Group(s)](https://geos-chem.seas.harvard.edu/geos-working-groups) directly. But if you do not know whom to ask, you may open a new issue (See "Where can I ask for help" above) and we will be happy to direct your question to the appropriate person(s).
