Base Building Blocks is easy to install just enable it. The latest version of Bootstrap is included in the repo, so you don't need to add any libraries or modules to make this theme work.
This project is meant to be a base theme, meaning it's built for you to take, and build-upon. :)
There's also a Base Building Blocks Module that ships with some cool stuff, like configurable Bootstrap Menu blocks (with dropdowns and icons), a Bootstrap administration navbar block, and more. It's pretty much a staple for using this theme.
