Celo Contributor Overview

Celo is open source and welcomes participation from everyone. We strive to fulfill our Community Tenets by being inclusive and empowering. All contributors must abide by Celo's Code of Conduct.

warning

As of block height 31,056,500 (March 26, 2025, 3:00 AM UTC), Celo is no longer a standalone Layer 1 blockchain—it is now an Ethereum Layer 2! Some documentation may be outdated as updates are in progress. If you encounter issues, please file a bug report.

For the most up-to-date information, refer to our Celo L2 documentation.

Ways to Contribute​

Our community welcomes contributors with diverse skills:

  • Code Contributors - Developers who improve Celo's protocol and infrastructure
  • CIP Contributors - Authors of Celo Improvement Proposals
  • Documentation Contributors - Writers who create and maintain technical documentation
  • Tutorial Authors - Community members who share experiences and create educational content

General Contribution Guidelines​

Whether you're contributing code, documentation, or other content, these principles apply:

  • Fork the repository - Always work in your own fork before submitting changes
  • Use PRs for changes - Pull requests are preferred, especially for small changes like typos
  • Work in branches - Use feature branches, not master/main, for ongoing work
  • Submit regularly - For non-trivial work, submit PRs regularly to get feedback
  • Quality matters - Double-check your work before submission
  • Be objective - Remain fact-based and neutral in tone

PR Best Practices​

For effective contributions:

  • Create meaningful PRs with clear descriptions
  • For works in progress, use "WIP" in the title
  • Request appropriate reviewers (check CODEOWNERS when unsure)
  • Explain dependencies and breaking changes
  • Include relevant tests and documentation updates

Tutorial Contributions​

Share your Celo experience through blog posts:

  • Create files in the blog directory using format YYYY-MM-DD-post-name.md
  • Include proper front matter (title, description, author info)
  • Use <!--truncate--> to define post summaries
  • For images, create a folder with the same naming convention containing your post (as index.md) and assets
