+# yaml-pretty-extras
+
+This library adds a ```toPrettyYaml``` typeclass and helper functions.
+
+## Example Usage
+
+```{.haskell}
+{-# LANGUAGE DeriveAnyClass    #-}
+{-# LANGUAGE DeriveGeneric     #-}
+{-# LANGUAGE OverloadedStrings #-}
+
+import Data.Yaml.Pretty.Extras
+import GHC.Generics
+
+data Foo = Foo {
+  bar :: Text,
+  quux :: Text
+} deriving (Eq, Show, FromJSON, ToJSON)
+
+instance ToPrettyYaml Foo where
+  fieldOrder = const ["quux", "bar"]
+
+main = encodeFilePretty "foo.yaml" (Foo "bar" "quux") -- prints out "quux: quux\nbar: bar"
