+# Contributing to xps-gateway
+
+We love your input! We want to make contributing to this project as easy and transparent as possible, whether it's:
+
+- Reporting a bug
+- Discussing the current state of the code
+- Submitting a fix
+- Proposing new features
+- Becoming a maintainer
+
+## We Develop with Github
+
+We use GitHub to host code, to track issues and feature requests, as well as accept pull requests.
+
+## We Use [Github Flow](https://guides.github.com/introduction/flow/index.html), So All Code Changes Happen Through Pull Requests
+
+Pull requests are the best way to propose changes to the codebase (we use [Github Flow](https://guides.github.com/introduction/flow/index.html)). We actively welcome your pull requests:
+
+1. Fork the repo and create your branch from `master`.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the documentation.
+4. Ensure the test suite passes.
+5. Make sure your code lints.
+6. Issue that pull request!
+
+## Any Contributions You Make Will Be Under the [Software License](LICENSE.md) Used in this Project
+
+In short, when you submit code changes, your submissions are understood to be under the same [license](LICENSE.md) that covers the project. Feel free to contact the maintainers if that's a concern.
+
+## Report Bugs Using Github's [Issues](https://github.com/xmtp/xps-gateway/issues)
+
+We use GitHub issues to track public bugs. Report a bug by [opening a new issue](https://github.com/xmtp/xps-gateway/issues); it's that easy!
+
+## Write Bug Reports With Detail, Background, and Sample Code
+
+**Great Bug Reports** tend to have:
+
+- A quick summary and/or background
+- Steps to reproduce
+  - Be specific!
+  - Give sample code if you can.
+- What you expected would happen
+- What actually happens
+- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)
+
+People _love_ thorough bug reports.
+
+## Use a Consistent Coding Style
+
+- Rust Language [Style Guide](https://doc.rust-lang.org/beta/style-guide/index.html)
+
+## Extremely high bar for unit test coverage
+
+- This project requires full test coverage for all changes
+
+## License
+
+By contributing, you agree that your contributions will be licensed as MIT open source.
