inResponse is a responsive Joomla! 2.5 template based on the Twitter Bootstrap framework. It's for people to learn how Joomla! templates work and as a basis for tinkering.
It's based on the excellent Twitter Bootstrap framework, which means it's responsive (try making your browser window narrower if you don't know what this means) and looks pretty.
inResponse is for a few different types of people. We hope it'll be used by people new to Joomla! who want to learn about how it works. It could also be used by developers/designers as a basis for all sorts of work. And it's for us.
