 The React repository includes several renderers. Each of them has its own host config.
 
 The examples in the React repository are declared a bit differently than a third-party renderer would be. In particular, the `HostConfig` object mentioned above is never explicitly declared, and instead is a *module* in our code. However, its exports correspond directly to properties on a `HostConfig` object you'd need to declare in your code:

 ### Hydration Methods
 
 You can optionally implement hydration to "attach" to the existing tree during the initial render instead of creating it from scratch. For example, the DOM renderer uses this to attach to an HTML markup.
