Getting started with Foundation and its settings file to make the most of SASS

I’m currently reading up on Foundation and the key differences between foundation and bootstrap. My first serious project is working with 5.5.3.

Because I mostly use plain html / css there is zero difference between the frameworks in terms of how I design - more Foundation is less bloated (out the box) - similar to bootstrap I can create my own custom version http://foundation.zurb.com/sites/download.html/

I only need the essentials, as my main reason for using a framework is to speed up my design process and the responsive aspect.
