HTML5 'Coming Soon' page with a simple, responsive design.
There is no build.
https://github.com/indexzero/http-server is an easy choice, but any web server will do.
git clone https://github.com/kanini/coming-soon.git
cd coming-soon
npm install --global http-server
http-server # defaults to port 8080, http://localhost:8080/index.html
