Add Jekyll config
Add dev instructions
Add basic layout

If you need to inject stuff here (ie. CSS, JS), add `{{ page.css }}`
type of statements to `_layouts/layout.html`. You can refer to these at
YAML headmatter (ie. `css: index`). It is also possible to use
conditional logic (`{% if page.url == '/' %}foobar{% endif %}`) to model
navigation etc.
