 ## Installation
 
+    npm install boiler.js
+
 
 ## Usage
 
+Once installed, add it to your project with common.js or ES6 syntax :
+
+```js
+    const Boiler = require("boiler.js");
+    // or
+    import Boiler from "boiler.js";
+```
+
+Then, you can start to use it on your code :
+
+```js
+    const boiler = new Boiler();
+```
+
+Since today's web browser don't support module requirements yet, you need to use a bundler like [webpack](https://webpack.js.org/) or [browserify](http://browserify.org/).
+
 
 ## CDN
 
+If you want to go old-school, you can fetch the script with [unpkg](https://unpkg.com/) or [jsdelivr](https://www.jsdelivr.com/).
+
+```html
+    <script src="https://unpkg.com/boiler.js"></script>
+    <!-- or -->
+    <script src="https://cdn.jsdelivr.net/npm/boiler.js"></script>
+    
+    <script>
+        console.log(new Boiler());
+    </script>
+```
