Kristo Jorgenson e67d62d888 Update styled-component docs (#841)
* Add details to custom Document documentation

Custom document must be created at ./Pages/_document.js, which is not
noted in the README… so I updated it.

* Add note to styled-components example about existing issue

* Made phrasing a bit more clear

* Another phrasing update.

# Example app with styled-components
## How to use
Download the example [or clone the repo](https://github.com/zeit/next.js):
```bash
curl https://codeload.github.com/zeit/next.js/tar.gz/master | tar -xz --strip=2 next.js-master/examples/with-styled-components
cd with-styled-components
```
Install it and run:
```bash
npm install
npm run dev
```
Deploy it to the cloud with [now](https://zeit.co/now) ([download](https://zeit.co/download))
```bash
now
```
## The idea behind the example
This example features how you use a different styling solution than [styled-jsx](https://github.com/zeit/styled-jsx) that also supports universal styles. That means we can serve the required styles for the first render within the HTML and then load the rest in the client. In this case we are using [styled-components](https://github.com/styled-components/styled-components).
For this purpose we are extending the `<Document />` and injecting the server side rendered styles into the `<head>`.
## Notes:
- On initial install, you may see a server-side error: `TypeError: Cannot read property 'cssRules' of undefined when using this line of code` until you actually render a `styled-component`. I have submitted a PR to fix this issue with them [here](https://github.com/styled-components/styled-components/pull/391). For the time being, make sure you render at least one `styled-component` when you use this.
