Setup Guide should indicate resources need to be moved to the distribution directory.

When installing DocJS and documenting an stylesheet, it is necessary to move:
- the demo
- the resources needed on the demo (css, img)

Currently in the guide we indicate that it is necessary to move just the demo. Ideally DocJS would take care of it, or a grunt task would need to be set. But until this is not done, we need to include this task as part of the guide.

Something to consider is to update the guide so that the stylesheet created can be easily moved to the `styleguide` directory with the `demo`. Currently we indicate to create the stylesheet under the `style` directory, but this is not practical if the `.md` files are also hosted in this location.
