-## Using `create-kaboom` to generate kaboom project
+# Installation
+
+The most easy way to get started with Kaboom is to use the [CLI tool](https://www.npmjs.com/package/create-kaboom), which will generate a Kaboom project for you:
 
 ```sh
 $ npm init kaboom -- mygame
+$ cd mygame
+$ npm run dev
 ```
 
-This will create a directory `mygame` containing everything you need to start a Kaboom project, go to that directory and run `npm run dev` to start the development server, and edit `src/main.js` to develop the game.
