+### Using the `startupHook`
+
+Instead of the `.xinitrc` file, one can also use XMonad's built in
+`startupHook` in order to auto start programs.  The
+[XMonad.Util.SpawnOnce] library is perfect for this use case, allowing
+programs to start only once, and not with every invocation of `M-q`!
+
+This requires but a small change in `myConfig`:
+
+``` haskell
+-- import XMonad.Util.SpawnOnce (spawnOnce)
+
+myConfig = def
+    { modMask     = mod4Mask       -- Rebind Mod to the Super key
