You are welcome to create, update and fix bugs in our [curriculum](#curriculum), help us fix bugs in freeCodeCamp.org's [learning platform](#learning-platform), or [help us translate](#translations) freeCodeCamp.org to world languages.
You can help expand and improve the curriculum. You can also update project user stories to better-explain concepts. And you can improve our automated tests so that we can more accurately test people's code.

Our learning platform runs on a modern JavaScript stack. It has various components, tools, and libraries. These include Node.js, MongoDB, OAuth 2.0, React, Gatsby, Webpack, and more.
Broadly, we have a Node.js based API server, a set of React-based client applications, testing scripts to evaluate camper-submitted curriculum projects, and more. If you want to productively contribute to the learning platform, we recommend some familiarity with these tools.
