Update README

Updated the template files and ran `grunt` to render the static output.

When I ran Grunt it threw a lot of changes to the files in `test/actual/`. The HTML string names like:
```
<li><a href="assets_base.html">assets_base.html</a></li>
```
Actually got output as:
```
<li><a href="assets_base.html">[object Object]</a></li>
```
Don't know if it's an actual issue, or if I'm doing it wrong.
