+
+A `FocusList` is a sequence of elements which has one element as its `Focus`. It
+supports quick insertion and indexing by its implementation with
+[`Seq`](http://hackage.haskell.org/package/containers-0.6.0.1/docs/Data-Sequence.html#t:Seq).
+
+## Example
+
+Here is a short example of using `FocusList`.
+
+```haskell
+module Main where
+
+import Data.FocusList
+  ( Focus(Focus), FocusList, appendFL, fromListFL, getFocusItemFL, prependFL
+  , singletonFL
+  )
+import Data.Foldable (toList)
+
+-- | Create a new 'FocusList' from a list.  You must set the 'Focus' of the new
+-- 'FocusList'.  The 'Focus' is counting from zero, so the @goat@ element should
+-- have the 'Focus'.
+--
+-- If you try to specify a 'Focus' out of range from the input list,
+-- 'fromListFL' will return 'Nothing'.
+myFocusList :: Maybe (FocusList String)
+myFocusList = fromListFL (Focus 2) ["hello", "bye", "goat", "dog"]
+
+-- | You can get the focused element from an existing 'FocusList'
+--
+-- If the 'FocusList' is empty, this returns 'Nothing'.
+myFocusElement :: FocusList String -> Maybe String
+myFocusElement focuslist = getFocusItemFL focuslist
+
+-- | You can append to either side of a 'FocusList'.
+--
+-- 'singletonFL' creates a 'FocusList' with a single element.
+-- That single element will have the 'Focus'.
+--
+-- 'myFocusListAppended' will have a value of
+-- @FocusList (Focus 1) ["bye", "hello", "foobar"]@
+myFocusListAppended :: FocusList String
+myFocusListAppended =
+  prependFL "bye" (appendFL (singletonFL "hello") "foobar")
+
+-- | 'FocusList' is an instance of 'Functor' and 'Foldable', so you can use
+-- functions like 'fmap' and 'toList' on a 'FocusList'.
+fmapAndConvertToList :: FocusList Int -> [String]
+fmapAndConvertToList focuslist = toList (fmap show focuslist)
+
+main :: IO ()
+main = do
+  putStrLn "myFocusList:"
+  print myFocusList
+
+  putStrLn "\nmyFocusListAppended:"
+  print myFocusListAppended
+
+  putStrLn "\nmyFocusElement myFocusListAppended:"
+  print (myFocusElement myFocusListAppended)
+
+  putStrLn "\nfmap length myFocusListAppended:"
+  print (fmap length myFocusListAppended)
+
+  putStrLn "\nfmapAndConvertToList (fmap length myFocusListAppended):"
+  print (fmapAndConvertToList (fmap length myFocusListAppended))
+```
