+- `/help` : Display help with all available commands
+- `/disconnect` : Clean server disconnection
+- `<message>` : Broadcast message translated to emojis to all connected clients
+
+### Technical Features
+
+- UDP Communication
+- Multi-threading for client handling
+- Mistral API for text-to-emoji conversion
+- Disconnection handling

 ### Client
 
 ```bash
-./gradlew run --args='client'
+./gradlew runClient
 ```
 
-or
+The client will ask for a pseudo, an IP (type `localhost` if server and clients are on the same machine), and a port (type `6666` by default).

 ### Server

 ```bash
 ./gradlew runServer

+## Configuration
+
+Create a `config.properties` file at project root (`ClientServer/app/config.properties`) with:
+
+```properties
+mistral.api.key=your_api_key
+```
+
+Replace `your_api_key` with your actual Mistral API key. Create one for free at https://console.mistral.ai/api-keys. If no API key is provided, the server will not be able to convert broadcasted messages to emojis and empty broadcasted messages will be sent.
