-## Usage
-
-```bash
-composer require symfony/ux-react
-
-# Don't forget to install the JavaScript dependencies as well and compile
-$ yarn install --force
-$ yarn encore dev
-```
-
-Then in your `assets/app.js` file, add the following lines:
-
-```
-// assets/app.js
-import { registerReactControllerComponents } from '@symfony/ux-react';
-
-// Registers React controller components to allow loading them from Twig
-//
-// React controller components are components that are meant to be rendered
-// from Twig. These component then rely on other components that won't be called
-// directly from Twig.
-//
-// By putting only controller components in `react/controllers`, you ensure that
-// internal components won't be automatically included in your JS built file if
-// they are not necessary.
-registerReactControllerComponents(require.context('./react/controllers', true, /\.(j|t)sx?$/));
-```
-
-You can now create your first React controller component in `assets/react/controllers`:
-
-```js
-// assets/react/controllers/MyComponent.jsx
-import React from 'react';
-
-export default function (props) {
-    return <div>Hello {props.fullName}</div>;
-}
-```
-
-And use it in your Twig files:
-
-```twig
-{# templates/home.html.twig #}
-
-<div {{ react_component('MyComponent', { 'fullName': app.user.fullName }) }}></div>
-```

 Symfony UX React
 ================
 
-TODO
+Symfony UX React is a Symfony bundle integrating `React`_ in
+Symfony applications. It is part of `the Symfony UX initiative`_.
+
+React is a JavaScript library for building user interfaces.
+Symfony UX React provides tools to render React components from Twig,
+handling rendering and data transfers.
+
+Installation
+------------
+
+Before you start, make sure you have `Symfony UX configured in your app`_.
+
+Then install the bundle using Composer and Symfony Flex:
+
+.. code-block:: terminal
+
+    $ composer require symfony/ux-react
+
+    # Don't forget to install the JavaScript dependencies as well and compile
+    $ yarn install --force
+    $ yarn encore dev
+
+You also need to add the following lines at the end to your ``assets/app.js`` file:
+
+.. code-block:: javascript
+
+    // assets/app.js
+    import { registerReactControllerComponents } from '@symfony/ux-react';
+
+    // Registers React controller components to allow loading them from Twig
+    //
+    // React controller components are components that are meant to be rendered
+    // from Twig. These component then rely on other components that won't be called
+    // directly from Twig.
+    //
+    // By putting only controller components in `react/controllers`, you ensure that
+    // internal components won't be automatically included in your JS built file if
+    // they are not necessary.
+    registerReactControllerComponents(require.context('./react/controllers', true, /\.(j|t)sx?$/));
+
+
+Usage
+-----
+
+UX React works by using a system of **React controller components**: React components that
+are registered using ``registerReactControllerComponents`` and that are meant to be rendered
+from Twig.
+
+When using the ``registerReactControllerComponents`` configuration shown previously, all
+React components located in the directory ``assets/react/controllers`` are registered as
+React controller components.
+
+You can then render any React controller component in Twig using the ``react_component``.
+For example:
+
+.. code-block:: javascript
+
+    // assets/react/controllers/MyComponent.jsx
+    import React from 'react';
+
+    export default function (props) {
+        return <div>Hello {props.fullName}</div>;
+    }
+
+
+.. code-block:: twig
+
+    {# templates/home.html.twig #}
+
+    <div {{ react_component('MyComponent', { 'fullName': app.user.fullName }) }}></div>
+
+Backward Compatibility promise
+------------------------------
+
+This bundle aims at following the same Backward Compatibility promise as
+the Symfony framework:
+https://symfony.com/doc/current/contributing/code/bc.html
+
+However it is currently considered `experimental`_,
+meaning it is not bound to Symfony's BC policy for the moment.
