+# Contribution Guidelines
+
+Hello! Thanks for your interest in joining the mission to accelerate the mass adoption of crypto for personal
+sovereignty! We welcome contributions from anyone on the internet, and are grateful for even the smallest of fixes!
+
+## Ways to contribute
+
+There are many ways to contribute to the ZK Stack:
+
+1. Open issues: if you find a bug, have something you believe needs to be fixed, or have an idea for a feature, please
+   open an issue.
+2. Add color to existing issues: provide screenshots, code snippets, and whatever you think would be helpful to resolve
+   issues.
+3. Resolve issues: either by showing an issue isn't a problem and the current state is ok as is or by fixing the problem
+   and opening a PR.
+4. Report security issues, see [our security policy](./github/SECURITY.md).
+5. [Join the team!](https://matterlabs.notion.site/Shape-the-future-of-Ethereum-at-Matter-Labs-dfb3b5a037044bb3a8006af2eb0575e0)
+
+## Fixing issues
+
+To contribute code fixing issues, please fork the repo, fix an issue, commit, add documentation as per the PR template,
+and the repo's maintainers will review the PR.
+[here](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork)
+for guidance how to work with PRs created from a fork.
+
+## Licenses
+
+If you contribute to this project, your contributions will be made to the project under both Apache 2.0 and the MIT
+license.
+
+## Resources
+
+We aim to make it as easy as possible to contribute to the mission. This is still WIP, and we're happy for contributions
+and suggestions here too. Some resources to help:
+
+1. [In-repo docs aimed at developers](docs)
+2. [zkSync Era docs!](https://era.zksync.io/docs/)
+3. Company links can be found in the [repo's readme](README.md)
+
+## Code of Conduct
+
+Be polite and respectful.
