+
+## Getting started
+
+### Prerequisites
+
+1. Git
+1. Node: install version 8.4 or greater
+1. Yarn: `npm i -g yarn` to install it globally via NPM
+1. A clone of the [reactjs.org repo](https://github.com/facebook/reactjs.org) on your local machine
+1. A fork of the repo (for any contributions)
+
+### Installation
+
+1. `cd reactjs.org` to go into the project root
+1. `yarn` to install the website's NPM dependencies
+
+### Running locally
+
+1. `yarn dev` to start the hot-reloading development server (powered by [Gatsby](https://www.gatsbyjs.org))
+1. `open http://localhost:8000` to open the site in your favorite browser
+
+## Contributing
+
+### Create a branch
+
+1. `git checkout master` from any folder in your local react repository
+1. `git pull origin master` to ensure you have the latest main code
+1. `git checkout -b the-name-of-my-branch` (replacing `the-name-of-my-branch` with a suitable name) to create a branch
+
+### Make the change
+
+1. Follow the "Running locally" instructions
+1. Save the files and check in the browser
+  1. Changes to React components in `src` will hot-reload
+  1. Changes to markdown files in `content` will hot-reload
+  1. If working with plugins, you may need to remove the `.cache` directory and restart the server
+
+### Test the change
+
+1. If possible, test any visual changes in all latest versions of common browsers, on both desktop and mobile.
+1. Run `yarn check-all` from the project root. (This will run Prettier, ESlint, and Flow.)
+
+### Push it
+
+1. `git add -A && git commit -m "My message"` (replacing `My message` with a commit message, such as `Fixed header logo on Android`) to stage and commit your changes
+1. `git push my-fork-name the-name-of-my-branch`
+1. Go to the [reactjs.org repo](https://github.com/facebook/reactjs.org) and you should see recently pushed branches.
+1. Follow GitHub's instructions.
+1. If possible include screenshots of visual changes. A Netlify build will also be automatically created once you make your PR so other people can see your change.
+
+## Troubleshooting
+
+- `yarn reset` to clear the local cache
