-## Overview
+## Setup
 
 This library includes three `history` object initializers for the different modes we support. They are:
 
-- [Browser history](#browserhistory)
-- [Hash history](#hashhistory)
-- [Memory history](#memoryhistory)
+- [Browser history](#browserhistory) - for building web apps
+- [Hash history](#hashhistory) - for building web apps where you don't want to/can't send the URL to the server for some reason
+- [Memory history](#memoryhistory) - for building native apps and testing
+
+An app should only ever need to use one of these modes.
