The Bootstrap theme allows developers to use Twitter's Bootstrap framework within their Nesta CMS app.
Currently under development.
Install the theme as a git submodule to get the benefits of future updates.
mysite$ git submodule add git://github.com/mchung/nesta-theme-bootstrap.git themes/bootstrap
And make sure your config/config.yml file (or NESTA_THEME env var) specifies the bootstrap theme.
The Nesta-approved installation method is to do:
mysite$ nesta theme:install git://github.com/mchung/nesta-theme-bootstrap.git
Future updates might not be easily propagated.
