-    This module lets you combine and switch between different types of prompts (`XMonad.Prompt.XPrompt`). It includes a set of default modes:
+    This module exemplifies usage of `XMonad.Prompt.mkXPromptWithModes`. It includes two modes:
 
        * Hoogle mode: Search for functions using hoogle, choosing a function leads you to documentation in Haddock.
 
-       * Locate mode: Search for files using locate, choosing a file opens it with a program you specify depending on the file's extension.
-
-       * Locate regexp: Same as locate mode but autocomplete works with regular expressions.
-
        * Calc: Uses the program calc to do calculations.
 
-    To use the default modes, modify your .xmonad:
