 1. Create the component in the `./react` directory
 2. Register the component for webpack in `./javascripts/index.js` so the component works with client side rendering
 3. Register the component in `./lib/react-engine.js` so the component works with server side rendering

 ## Gotchas

+- When requiring React components from npm you will often need to explicitly call `require('component').default` to make sure you get the component 
 - Some code examples you get from external React packages won't work out of the box, you often need to dig into the module and determine whether it's exporting to default or not which will in many cases cause you to need to `require('package').default`
 - `import` doesn't always work. Use `require` for a more consistent experience with React in this codebase.
 - If components require you to load CSS, you need to load that CSS in the `javascripts/index.js` file as shown [here](https://github.com/github/docs/blob/a48998c7890b71c8f58eda1fa31b50df348a0042/javascripts/index.js#L22)
