Welcome to Free Code Camp's open source codebase!

Free Code Camp is an open-source community of busy people who learn to code, then build projects for nonprofits.

Our campers (students) start by working through our free, self-paced, browser-based curriculum. Next, they build several practice projects. Finally, we pair two campers together with a stakeholder from a nonprofit organization, and help them build the solution the nonprofit has requested.

We help our campers build job-worthy portfolios of real apps used by real people, while helping nonprofits.

80% of our campers are over 25, and nearly a fifth of our campers are women.

This code is running live at FreeCodeCamp.com. We also have Slack, a blog, and even a Twitch.tv channel.

Join our community!

Contributing

We welcome pull requests from Free Code Camp campers (our students) and seasoned JavaScript developers alike! Follow these steps to contribute:

Check our public Waffle Board.
Pick an issue that nobody has claimed and start working on it. If your issue isn't on the board, open an issue. If you think you can fix it yourself, start working on it. Feel free to ask for help in our Slack.
Fork the project (Need help with forking a project?). You'll do all of your work on your forked copy.
Create a branch specific to the issue or feature you are working on. Push your work to that branch. (Need help with branching?)
Name the branch something like user-xxx where user is your username and xxx is the issue number you are addressing.
You should have ESLint running in your editor, and it will highlight anything doesn't conform to AirBnB's JavaScript Style Guide. Please do not ignore any linting errors, as they are meant to help you. Make sure none of your JavaScript is longer than 80 characters per line.
Once your code is ready, submit a pull request from your branch to Free Code Camp's staging branch. We'll do a quick code review and give you feedback, then iterate from there.
Once we accept one of your pull requests, one of the project owners (currently @quincylarson, @terakilobyte, and @berkeleytrue) will add you to our camper contributor group.

Prerequisites

Getting Started

The easiest way to get started is to clone the repository:

# Get the latest snapshot
git clone --depth=1 https://github.com/freecodecamp/freecodecamp.git freecodecamp

cd freecodecamp

# Install NPM dependencies
npm install
