code/content for explainers for DotEveryone.
A Sinatra application designed for deployment onto your PAAS of a choice (though really, it's just a stack of flat pages).
You'll need bundler installed. Then:
bundle install
from the application directory will install everything you need, and
bundle exec rackup
will run a local server at localhost:9292 and you can tweak to your heart's content. (If you prefer a server that will live-reload server.rb when it changes, you will want to bundle exec shotgun.
Note that styles are composed in scss/gisborough.scss . Compass will compile them into CSS for you - just run bundle exec compass watch from the application directory to sit and generate full-fat CSS as necessary. Both compiled CSS and original SCSS are checked into Github.
