 Here we create our WebGLRenderer, we pass it the size of the window as a parameter and then append it to the DOM.
+```
+// BASIC SETUP
+// ------------------------------------------------
+
+// Create an empty scene
+var scene = new THREE.Scene();
+
+// Create a basic perspective camera
+var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );
+camera.position.z = 4;
+
+// Create a renderer with Antialiasing
+var renderer = new THREE.WebGLRenderer({antialias:true});
+
+// Configure renderer clear color
+renderer.setClearColor("#ff0000");
+
+// Configure renderer size
+renderer.setSize( window.innerWidth, window.innerHeight );
+
+// Append Renderer to DOM
+document.body.appendChild( renderer.domElement );
+```
+
+Here we create our WebGLRenderer, we pass it the size of the window as a parameter and then append it to the DOM. The **empty scene** is where we are going to add our objects. And by last we create a camera, passing as parameters the FOV, the Aspect ratio and the near plane and far plan. 
 
+Once this is done we have the 3 fundamental elements of a Three.js application.
