In the command prompt/terminal use the following commands to setup the project:
bundle install- this will install the required gems
npm install- this will install the modules for Grunt
grunt watch- this monitors your assets for changes then compiles them
npm install dploy -g- this is for deployment. Modify dploy.yaml to reflect your environments - http://leanmeanfightingmachine.github.io/dploy/
That's it. You can use this as the starting point for a static site, or drop it into a WordPress theme.
