These libraries look really good, especially for Rellax for parallax effects.

I'll apologise in advance for the unsolicited advice, but please do consider not modifying native scroll behaviour. It breaks something that works (and conforms to user expectations) for, in many cases, a poorer user experience. It forces a particular temporality on the and takes control away from her.

I'm sure you were not planning on scroll-jacking, but since I see scroll animation libraries abused so much (even by Apple for the Mac Pro!;it's rather frustrating), I thought I'd mention.

I use Metalsmith. It's a very bare-bones static site generator where everything is a plugin. So you get to define your own workflow.

A workflow could be:

1. Take Markdown files from a source directory
2. Get the right template (written in pretty much any templating language)
3. Update all links
4. Generate pretty permalinks
5. Generate the whole website
6. Deploy and go live.

You could, technically, use themes, but I don't know how many you'll find out in the wild. Everyone has their own personal workflow/templates.

I've written a beginner-level Metalsmith tutorial on my blog (which itself is powered by Metalsmith), if you're interested.
