This repository contains the Nesta project that is running on effectif.com. Feel free to have a dig around to get a feel for how to tweak Nesta.
If you fancy making your own site like this, please don't fork this one. You'd be better off installing the nesta gem and creating your own project from scratch:
$ gem install nesta
$ nesta new mydomain.com # run nesta -h for options
$ cd mydomain.com
$ git init
