 # Usage
 The Gooey system is encapsulated in a single Lua module without any visual components. It makes very little assumptions of the look and feel of the UI components it supports. Instead Gooey focuses on providing stable input and state handling and lets the user decide which states matter and how they should be presented visually.

-## Gooey Themes
-Gooey comes shipped with two themes: Dirty Larry and Kenneyblue. You can use these as they are or make a copy and modify. Each theme consists of a Lua module wrapping Gooey, a couple of GUI templates, a font and an atlas containing the visual representation of the components. Use the themes like this:
-
-	local kenneyblue = require "gooey.themes.kenneyblue.kenneyblue"
-
-	function on_input(self, action_id, action)
-		kenneyblue.button("button", action_id, action, function(button)
-			print("pressed button")
-		end)
-	end
