+
+{- $configure
+
+xmonad is configure by creating and editing the Haskell file:
+
+>    ~/.xmonad/xmonad.hs
+
+xmonad then uses default settings from this file as arguments to the
+window manager.
+
+-}
+
+{- $example
+
+Here is a basic example, which takes defaults from xmonad, and overrides 
+the border width, default terminal, and some colours:
+
+>    --
+>    -- An example, simple ~/.xmonad/xmonad.hs file.
+>    -- It overrides a few basic settings, reusing all the other defaults,
+>    -- 
+>
+>    import XMonad
+>
+>    main = xmonad $ defaultConfig
+>        { borderWidth        = 2
+>        , terminal           = "urxvt"
+>        , normalBorderColor  = "#cccccc"
+>        , focusedBorderColor = "#cd8b00" }
+
+This will run \'xmonad\', the window manager, with your settings passed as
+arguments.
+
+Overriding default settings like this (using \"record update syntax\"),
+will yield the shortest config file, as you only have to describe values
+that differ from the defaults.
+
+An alternative is to inline the entire default config file from xmonad,
+and edit values you wish to change. This is requires more work, but some
+users may find this easier. You can find the defaults in the file:
+
+>    XMonad/Config.hs
+
+-}
+
+{- $check
+
+Place this text in @~/.xmonad/xmonad.hs@, and then check that it is
+syntactically and type correct, by loading it in the Haskell
+interpreter:
+
+>    $ ghci ~/.xmonad/xmonad.hs  
+>    GHCi, version 6.8.1: http://www.haskell.org/ghc/  :? for help
+>    Loading package base ... linking ... done.
+>    Ok, modules loaded: Main.
+>
+>    Prelude Main> :t main
+>    main :: IO ()
+
+Ok, looks good.  
+
+-}
+
+{- $load
+
+To have xmonad start using your settings, try @mod-q@. xmonad will
+attempt to compile this file, and run it. If it is unable to, the
+defaults are used. This requires GHC and xmonad are in your @$PATH@
+settings. If GHC isn't in your path, you can still compile the
+@xmonad.hs@ file yourself:
+
+>    $ cd ~/.xmonad
+>    $ ghc --make xmonad.hs
+>    $ ls
+>    xmonad    xmonad.hi xmonad.hs xmonad.o
+
+When you hit @mod-q@, this newly compiled xmonad will be used.
+
+-}
+
+{- $where
+
+The default configuration values are defined in the source file:
+
+>   XMonad/Config.hs 
+
+the 'XMonad.Core.XConfig' data structure itself is defined in:
+
+>    XMonad/Core.hs
+
+See "XMonad.Core".

+{- $extending
+
+Extending XMonad
+
+Since the @xmonad.hs@ file is just another Haskell module, you may
+import and use any Haskell code or libraries you wish, such as
+extensions from the xmonad-contrib library, or other code you write
+yourself.
+
+-}
+
+{- $keys
+
+Editing key bindings means changing the 'XMonad.Core.XConfig.keys'
+record of the 'XMonad.Core.XConfig' data type, like:
+
+>    main = xmonad defaultConfig { keys = myKeys }
+
+and by providing a proper definition of @myKeys@ such as:
+
+>       myKeys x   = 
+>          [ ((modMask x              , xK_F12   ), xmonadPrompt      defaultXPConfig    )
+>          , ((modMask x              , xK_F3    ), shellPrompt       defaultXPConfig    )
+>          ]
+
+Remember that this definition requires importing "Graphics.X11.Xlib",
+"XMonad.Prompt", "XMonad.Prompt.Shell", and "XMonad.Prompt.XMonad"
+
+-}
+
+{- $keyAdding
+
+Adding key bindings can be done in different ways. The type signature
+of "XMonad.Core.XConfig.keys" is:
+
+> keys :: XConfig Layout -> M.Map (ButtonMask,KeySym) (X ())
+
+which means you need to use 'Data.Map.insert' in order to add some
+bindings to the map of the existing key bindings.
+
+For instance, if you have defined some additional key bindings like
+these:
+
+>       myKeys x   = 
+>          [ ((modMask x              , xK_F12   ), xmonadPrompt      defaultXPConfig    )
+>          , ((modMask x              , xK_F3    ), shellPrompt       defaultXPConfig    )
+>          ]
+
+you may wish to edit accordingly the default configuration
+'XMonad.Core.XConfig.keys' record:
+
+>    main = xmonad defaultConfig { keys = newKeys }
+>           where newKeys x  = foldr (uncurry Data.Map.insert) (keys defaultKeys) (myKeys x)
+
+And that's it.
+
+At the end you @~\/.xmonad\/xmonad.hs@ would look like this:
+
+
+> module Main (main) where
+> 
+> import XMonad
+> 
+> import qualified Data.Map as M
+> import Graphics.X11.Xlib
+> import XMonad.Prompt
+> import XMonad.Prompt.Shell
+> import XMonad.Prompt.XMonad
+>
+> main :: IO ()
+> main = xmonad defaultConfig { keys = newKeys }
+>        where newKeys x  = foldr (uncurry M.insert) (keys defaultConfig x) (myKeys x)
+>
+> myKeys x   =
+>         [ ((modMask x              , xK_F12   ), xmonadPrompt      defaultXPConfig    )
+>         , ((modMask x              , xK_F3    ), shellPrompt       defaultXPConfig    )
+>          ]                                                                             
+
+
+Alternatively you may wish to use some of the utilities provided by
+the xmonad-contrib library.
+
+For instance, "XMonad.Util.EZConfig" and "XMonad.Util.CustomKeys"
+provide useful function to edit you key bindings.
