As part of our effort to better document and educate people about what concrete5 can do and how it does it, I've put together a brief how-to on concrete5 and Twitter Bootstrap. Version 5.5 uses the Bootstrap library (open-sourced by Twitter) as a way to create attractive UI elements like forms, popovers, navigations, etc... This how-to talks a little about Bootstrap and how it interacts with concrete5, how we customize it, and how links to some relevant documentation on how you can use it in your own blocks and add-ons
