-_An application running with [Kuzzle](https://github.com/kuzzleio/kuzzle)_
+## Why Kuzzle ?
+
+Kuzzle is a [generic backend](https://docs.kuzzle.io/core/2/guides/introduction/general-purpose-backend/) offering **the basic building blocks common to every application**.
+
+Rather than developing the same standard features over and over again each time you create a new application, Kuzzle proposes them off the shelf, allowing you to focus on building **high-level, high-value business functionalities**.
+
+Kuzzle enables you to build modern web applications and complex IoT networks in no time.
+
+* **API First**: use a standardised multi-protocol API.
+* **Persisted Data**: store your data and perform advanced searches on it.
+* **Realtime Notifications**: use the pub/sub system or subscribe to database notifications.
+* **User Management**: login, logout and security rules are no more a burden.
+* **Extensible**: develop advanced business feature directly with the integrated framework.
+* **Client SDKs**: use our SDKs to accelerate the frontend development.
+
+Learn how Kuzzle will accelerate your developments :point_right: https://docs.kuzzle.io/core/2/guides/introduction/what-is-kuzzle/
+
+## Kuzzle in production
+
+Kuzzle is production-proof, and can be [deployed anywhere](https://kuzzle.io/products/by-features/on-premises/).
+
+With Kuzzle, it is possible to deploy applications that can serve tens of thousands of users with very good performances.
+
+Check out our [support plans](https://kuzzle.io/pricing/).
 
 ## Installation and run
 
@@ -10,10 +41,72 @@ Requirement:
  - Docker
  - Docker-Compose
 
-First, install [Kourou](https://github.com/kuzzleio/kourou), the Kuzzle CLI: `npm install -g kourou`
-
 # Usage
 
 ```bash
 docker compose up -d
-```
+```
+
+## Use the framework
+
+Your first Kuzzle application is inside the `app.ts` file.
+
+For example, you can add a new [API Controller](https://docs.kuzzle.io/core/2/guides/develop-on-kuzzle/api-controllers):
+
+```ts
+import { Backend } from 'kuzzle';
+
+const app = new Backend('playground');
+
+app.controller.register('greeting', {
+  actions: {
+    sayHello: {
+      handler: async request => `Hello, ${request.input.args.name}`
+    }
+  }
+});
+
+app.start()
+  .then(() => {
+    app.log.info('Application started');
+  })
+  .catch(console.error);
+```
+
+Now try to call your new API action by:
+ - opening the generated URL in your browser: http://localhost:7512/_/greeting/say-hello?name=Yagmur
+ - using Kourou: `npx kourou greeting:sayHello --arg name=Yagmur`
