+## Getting Started

 Learn more about Yesod on [its main website](http://www.yesodweb.com/). If you
 want to get started using Yesod, we strongly recommend the [quick start
 guide](http://www.yesodweb.com/page/quickstart), based on [the Haskell build
 tool stack](https://github.com/commercialhaskell/stack#readme).
 
+Here's a minimal example!
+
+```haskell
+{-# LANGUAGE OverloadedStrings, QuasiQuotes, TemplateHaskell, TypeFamilies #-}
+
+import Yesod
+
+data App = App -- Put your config, database connection pool, etc. in here.
+
+-- Derive routes and instances for App.
+mkYesod "App" [parseRoutes|
+/ HomeR GET
+|]
+
+instance Yesod App -- Methods in here can be overridden as needed.
+
+-- The handler for the GET request at /, corresponds to HomeR.
+getHomeR :: Handler Html
+getHomeR = defaultLayout [whamlet|Hello World!|]
+
+main :: IO ()
+main = warp 3000 App
+```
+
+To read about each of the concepts in use above (routing, handlers,
+linking, JSON), in detail, visit
