+## What is RFS?
+RFS (abbreviation for responsive font size) is the name of the algorithm behind the mixin. It's also used by 
+[PostCSS RFS](https://github.com/MartijnCuppens/postcss-rfs).
 
 ## Advantages
 - Font sizes will **rescale for every screen width**, this prevents long words from being chopped off the screen on 
 mobile devices.
-- The minimum font size will prevent the font size from becoming too small so readability can be assured.
+- The minimum font size (configuration variable) will prevent the font size from becoming too small so readability can

 - **Super easy** to use, no need to define complex configurations for each font size.
 - Font sizes of all text elements will always remain in relation with each other.
