How to contribute

We love pull requests. And following this guidelines will make your pull request easier to merge.

If you want to contribute but don’t know what to do, take a look at these two labels: help wanted and good first issue.

Prerequisites

Install EditorConfig plugin for your code editor to make sure it uses correct settings.
Fork the repository and clone your fork.
Install dependencies: npm install.

Run linters and tests:

Or run tests in watch mode:

npm run test:watch

To update Jest snapshots:

Don’t forget to add tests and update documentation for your changes.

If you have commit access to repository and want to make big change or not sure about something, make a new branch and open pull request.
