    ( -- * Usage:
      -- $usage
      Simplest (..)
    ) where

import qualified XMonad.StackSet as S

-- $usage
-- You can use this module with the following in your
-- @xmonad.hs@:
--
-- > import XMonad.Layout.Simplest
--
-- Then edit your @layoutHook@ by adding the Simplest layout:
--
-- > myLayout = Simplest ||| Full ||| etc..
-- > main = xmonad def { layoutHook = myLayout }
--
-- For more detailed instructions on editing the layoutHook see
-- <https://xmonad.org/TUTORIAL.html#customizing-xmonad the tutorial> and
-- "XMonad.Doc.Extending#Editing_the_layout_hook".
