 - Now just `require "REST"`, it defines a global named `REST`
 - If you wish to use **module-loader** into your project, just delete the `require module-loader` from REST.lua (First line)
 
+## Simple Example

+Here is a simple example of using it in a love-game. Let's imagine you have recursive-cloned this repo to a sub-folder in your game: `lib/REST-love`:
+
+```lua
+-- this lets you require things with different paths other than root
+require "lib.REST-love.module-loader"
+
+-- this adds REST global
+requireFromLib("lib/REST-love", "REST")
+
+function love.load()
+  REST.get("https://mycoolserver.com/api", nil, function(data)
+   -- Do something here with data. It's text.
+  end)
+end
+
+function love.update(dt)
+  -- this is needed to trigger pending callbacks
+  -- it's wrapped with pcall to prevent it from crashing game
+  pcall(function() REST.retrieve(dt) end)
+end

 ## AsyncLoader
 AsyncLoader(Actually CoroutineLoader) is meant to be used by the LoadBar module, but you can extend its use yourself, you can use that
