+# Getting started with the Interactivity API
+
+To get started with the Interactivity API, you can follow this [**Quick Start Guide**](#) by taking into account the [current requirements of the Interactivity API](#) (especially the need for Gutenberg 16.2 or superior).
+
+## Quick Start Guide
+
+### 1. Scaffold an interactive block
+
+We can scaffold a WordPress plugin that registers an interactive block (using the Interactivity API) by using a [template](https://www.npmjs.com/package/@wordpress/create-block-interactive-template) with the `@wordpress/create-block` command.
+
+```
+npx @wordpress/create-block my-first-interactive-block --template @wordpress/create-block-interactive-template
+```
+
+### 2. Generate the build 
+
+When the plugin folder is generated, we should launch the build process to get the final version of the interactive block that can be used from WordPress. 
+
+```
+cd my-first-interactive-block && npm start
+```
+
+### 3. Use it in your WordPress installation 
+
+If you have a local WordPress installation already running, you can launch the commands above inside the `plugins` folder of that installation. If not, you can use [`wp-now`](https://github.com/WordPress/playground-tools/tree/trunk/packages/wp-now) to launch a WordPress site with the plugin installed by executing from the generated folder (and from a different terminal window or tab) the following command
+
+```
+npx @wp-now/wp-now start 
+```
+
+At this point you should be able to insert the "Example Interactive" block into any post, and see how it behaves in the frontent when published. 
+
+## Requirements of the Interactivity API
+
+To start working with the Interactivity API you'll need to have a [proper WordPress development environment for blocks](https://developer.wordpress.org/block-editor/getting-started/devenv/) which should include:
+
+- A local WordPress installation
+- Gutenberg 16.2 or superior
+- Node v14
+
+### A local WordPress installation
+
+You can use [the tools to set your local WordPress environment](https://developer.wordpress.org/block-editor/getting-started/devenv/#wordpress-development-site) you feel more comfortable with. 
+
+To get quickly started, [`wp-now`](https://github.com/WordPress/playground-tools/tree/trunk/packages/wp-now) is the easiest way to get a WordPress site up and running locally. 
+
+### Gutenberg 16.2 or superior
+
+The Interactivity API is currently only available as an experimental feature from Gutenberg 16.2, so you'll need to have the Gutenberg plugin with this version or a superior one, installed and activated in your WordPress installation.
+
+### Node v14
+
+Block development requires Node, so you also need to ensure you have [the proper version of Node](https://developer.wordpress.org/block-editor/getting-started/devenv/#node-development-tools) installed and running on your machine
