+## Hello world
+JSON2Video makes video creation easy as a piece of cake:
+
+```javascript
+    const {Movie, Scene} = require("json2video-sdk");
+    
+    // Create a new movie
+    let movie = new Movie;
+
+    // Set your API key
+    // Get your free API key at https://json2video.com
+    movie.setAPIKey(YOUR_API_KEY);
+
+    // Set a project ID
+    movie.set("project", "myproj");
+
+    // Set movie quality: low, medium, high
+    movie.set("quality", "high");
+
+    // Create a new scene
+    let scene = new Scene;
+
+    // Set the scene background color
+    scene.set("background_color",  "#4392F1");
+
+    // Add a text element printing "Hello world" in a fancy way (basic/006)
+    // The element is 10 seconds long and starts 2 seconds from the scene start
+    // Element's vertical position is 50 pixels from the top
+    scene.addElement({
+        type: "text",
+        template: "basic/006",
