It is almost amazing that I still see a lot of frontend developers still holding out on Sass or even holding on to Ruby/Gem versions of Sass preprocessor. Even those who reluctantly made a switch to modern gulp based Sass, use some very basic task functions, usually without understanding what is there also available.
The mission of this track will not be to teach you how to use Bootstrap as base theme, it will be first about setting up healthy directory structure and workflow for frontend development, then to learn about some useful tasks that are available to you with modern gulp plugins and lastly, how to put Bootstrap on diet and use only those parts that you actually need or make you own class names with Bootstrap mixins.
Prepare your questions and comments, I'd be glad to clear things for you :)
