 # Interactivity API
 
-> **Warning**
-> **This package is only available in Gutenberg** at the moment and not in WordPress Core as it is still very experimental, and very likely to change. 
+> **Note**
+> This package enables the API shared at [Proposal: The Interactivity API – A better developer experience in building interactive blocks](https://make.wordpress.org/core/2023/03/30/proposal-the-interactivity-api-a-better-developer-experience-in-building-interactive-blocks/). As part of an [Open Source project](https://developer.wordpress.org/block-editor/getting-started/faq/#the-gutenberg-project), participation is encouraged in testing this API providing feedback at the [discussions in GitHub](https://github.com/WordPress/gutenberg/discussions/categories/interactivity-api).
+
+The Interactivity API is available at WordPress Core from version 6.5 [Merge announcement](https://make.wordpress.org/core/2024/02/19/merge-announcement-interactivity-api/)
+
+These Core blocks are already powered by thi API:

+- Query
+- Navigation

 > **Note**
-> This package enables the API shared at [Proposal: The Interactivity API – A better developer experience in building interactive blocks](https://make.wordpress.org/core/2023/03/30/proposal-the-interactivity-api-a-better-developer-experience-in-building-interactive-blocks/). As part of an [Open Source project](https://developer.wordpress.org/block-editor/getting-started/faq/#the-gutenberg-project) we encourage participation in helping shape this API and the [discussions in GitHub](https://github.com/WordPress/gutenberg/discussions/categories/interactivity-api) is the best place to engage.
+> This step is only required if you are using this API outside of WordPress.
+>
+> Within WordPress, the package is already bundled in Core, so all you need to do to ensure it is loaded, by adding `wp-interactivity` to the dependency array of the module script.
+>
+>This happens automatically when you use the dependency extraction Webpack plugin that is used in tools like wp-scripts.
+
+Install the module:
+
+```bash
+npm install @wordpress/interactivity --save
+```
+
+_This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for such language features and APIs, you should include [the polyfill shipped in `@wordpress/babel-preset-default`](https://github.com/WordPress/gutenberg/tree/HEAD/packages/babel-preset-default#polyfill) in your code._
+
+## Quick Start Guide
 
-This package can be tested, but it's still very experimental.
-The Interactivity API is [being used in some core blocks](https://github.com/search?q=repo%3AWordPress%2Fgutenberg%20%40wordpress%2Finteractivity&type=code) but its use is still very limited.

-## Frequently Asked Questions 
+#### 1. Scaffold an interactive block
 
-At this point, some of the questions you have about the Interactivity API may be:
+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) can be scaffolded with the `@wordpress/create-block` command.
 
-### What is this?
+```
+npx @wordpress/create-block@latest my-first-interactive-block --template @wordpress/create-block-interactive-template
+```
 
-This is the base of a new standard to create interactive blocks. Read [the proposal](https://make.wordpress.org/core/2023/03/30/proposal-the-interactivity-api-a-better-developer-experience-in-building-interactive-blocks/) to learn more about this.
+#### 2. Generate the build
 
-### Can I use it?
+When the plugin folder is generated, the build process needs to be launched to get a working version of the interactive block that can be used in WordPress.
 
-You can test it, but it's still very experimental.
+```
+cd my-first-interactive-block && npm start
+```
 
-### How do I get started?
+#### 3. Use it in your WordPress installation
 
-The best place to start with the Interactivity API is this [**Getting started guide**](https://github.com/WordPress/gutenberg/blob/trunk/packages/interactivity/docs/1-getting-started.md). There you'll will find a very quick start guide and the current requirements of the Interactivity API.
+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
 
-### Where can I ask questions?
+```
+npx @wp-now/wp-now start
+```
 
-The [“Interactivity API” category](https://github.com/WordPress/gutenberg/discussions/categories/interactivity-api) in Gutenberg repo discussions is the best place to ask questions about the Interactivity API.
+At this point you should be able to insert the "My First Interactive Block" block into any post, and see how it behaves in the frontend when published.
 
-### Where can I share my feedback about the API?
+### Requirements of the Interactivity API
 
-The [“Interactivity API” category](https://github.com/WordPress/gutenberg/discussions/categories/interactivity-api) in Gutenberg repo discussions is also the best place to share your feedback about 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/) and some specific code in your block, which should include:
 
-## Installation
+#### A local 6.5 WordPress installation
 
-Install the module:
+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.
 
-```bash
-npm install @wordpress/interactivity --save
+To get quickly started, [`wp-now`](https://www.npmjs.com/package/@wp-now/wp-now) is the easiest way to get a WordPress site up and running locally.
+
+Interactivity API is included in Core in WordPress 6.5, for versions below, you'll need to have Gutenberg 17.5 or higher version installed and activated in your WordPress installation.
+
+#### Node.js
+
+Block development requires [Node](https://nodejs.org/en), so you'll need to have Node installed and running on your machine. Any version modern should work, but please check the minimum version requirements if you run into any issues with any of the Node.js tools used in WordPress development.
+
+#### Code requirements
+
+##### Add `interactivity` support to `block.json`
+
+To indicate that the block [supports](https://developer.wordpress.org/block-editor/reference-guides/block-api/block-supports/) the Interactivity API features, add `"interactivity": true` to the `supports` attribute of the block's `block.json`
+
+```
+"supports": {
+    "interactivity": true
+},
 ```
 
-_This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for such language features and APIs, you should include [the polyfill shipped in `@wordpress/babel-preset-default`](https://github.com/WordPress/gutenberg/tree/HEAD/packages/babel-preset-default#polyfill) in your code._
+##### Add `wp-interactive` directive to a DOM element
+
+To "activate" the Interactivity API in a DOM element (and its children), add the [`wp-interactive` directive](./docs/api-reference.md#wp-interactive) to it from `render.php` or `save.js`
