This the source of the devopsdays.org website It uses webby as a framework:

$ git clone [email protected]:jedi4ever/devopsdays-webby.git

$ yum install oniguruma oniguruma-devel

$ apt-get install libonig-dev

$ brew install oniguruma

• there is an .rvmrc that select ruby-1.8.7
• and creates a new gemset devopsdays-webby

$ git clone [email protected]:jedi4ever/devopsdays-webby.git

$ cd devopsdays-webby

$ gem install bundler

$ bundle install

$ . devopsdays-webby.ENV
$ gem install bundler
$ bundle install

All interactions are done with the webby command, for this you need to be inside the 'site' directory $ cd site

webby autobuild          # Continuously build the website
webby build              # Build the website
webby rebuild            # Build the website
