-// Need to add to the readme something along the lines of:
-//
-// The dropdown adapts to screen size. It more or less follows the breakpoints
-// of Bootstrap (need to list them). The code is written mobile-first. The
-// larger the screen size, the more rules we add to overwrite the previous one,
-// moving from one to two column.
-//
-// It is expected that the page layout also follow those breakpoints. The
-// breakpoints are defined as variables in the SCSS, so one can update them.
+// The dropdown adapts to screen size, to provide three different displays.
+// - A simple list of matching results
+// - Same list, but with text snippetting added if size is large enough
+// - Adding a second colum to let the content breath if enough room available
 
 // Main autocomplete wrapper
