I got stuck for a while on not being able to set up a global method due to process.envs not being able to be destructured. Hope to allow others not to spend as much time on it as I did!

- fix runtime configuration example to use `customKey`
- standardize warning callouts to use a block quote and bold "**Warning:**" text. Previously there were different ways a warning was mentioned on the docs page:
  - A warning emoji. The warning emoji didn't render in the actual site.

* Adde example on how to rendering muiltiple items carousel on server-side with nextjs

Hi everyone :)
I just updated Sentry to v5 and added @sentry/integrations due to breaking changes :)
I also fix the documentation. npm commands were in yarn section.

This merge request updates `fastify` package from v1 to v2 and adds the `cross-env` package so `NODE_ENV=` can work on Windows as well as OSX/Linux. Also adds example build output to GITIGNORE

Worth mentioning that pressing `a` will bring up a page that says `b` and vice-versa, but this seems to be the logic from the previous example as well. Can change if wanted

As requested in this issue: https://github.com/zeit/next.js/issues/6850

This is a basic HTTP2 server which can handle the `/` and `/about` routes. 

The Readme includes [specific instruction](https://github.com/shahzeb1/next.js/blob/31877720f076b49b39a167deb0ba8650d0052dda/examples/with-http2/README.md#download-manually) about how to generate the public/private keys used for this demo server.

This introduces the `useRouter` hook alternative to `withRouter`
