About Community Notes
Community Notes aims to create a better informed world, by empowering people on Twitter to add helpful notes to Tweets that might be misleading.
We're building it in the open, with the public’s input, and we’re taking significant steps to make Community Notes transparent.

Our goal is to expand Community Notes globally. We want anyone to be able to participate and know that having contributors with different points of view is essential to Community Notes helpfully addressing misinformation.
As there are important nuances in each market, we’ll expand the contributor base country-by-country. We’ll add contributors from a first new country soon.
How to contribute to this repo
Thank you for your interest in contributing to Community Notes! Currently, we will consider pull requests that contribute to the following areas:
- Downstream analyses of scoring model output
- Alternate scoring algorithm ideas (outside the core algorithm)
- Open issues
Note that we aren’t currently accepting changes that alter existing APIs, as there is other utility and production infrastructure code at Twitter that depends on these APIs remaining stable.
We are also exploring ways to make it easier for people to contribute directly to the core algorithm. For example, by making available testing and evaluation frameworks that would allow open source contributors to evaluate the impact of their PRs on note quality.
The markdown files in this repo are the source of truth for the content in our documentation website (aka "Community Notes Guide"). They are always updated here first, then ingested by Twitter's internal tools, translated, and published in communitynotes.twitter.com/guide.
