+# Module `cast`
+
+Ce module permet de communiquer avec des appareils de présentation de type [Chromecast](https://store.google.com/fr/product/chromecast_setup?hl=fr).
+
+## Méthodes
+
+### `cast.refreshDevices(timeout?: string = '30s'): Promise<Device[]>`
+
+Rafraichit la liste locale des appareils de présentation disponibles sur les réseaux locaux de la borne.
+
+L'appel à cette méthode rafraîchit également la liste mise en cache et renvoyée par `cast.getDevices()`.
+
+### `cast.getDevices(): []Device`
+
+Retourne la liste mise en cache des appareils de présentation disponibles sur les réseaux locaux de la borne.
+
+La liste est initialement vide. Un appel initial à `cast.refreshDevices()` est nécessaire afin de mettre à jour celle ci.
+
+### `cast.loadUrl(deviceUuid: string, url: string, timeout?: string = '30s'): Promise<void>`
+
+Charge l'URL donnée sur l'appareil de présentation identifié par l'UUID `deviceUuid`.
+
+### `cast.stopCast(deviceUuid: string, timeout?: string = '30s'): Promise<void>`
+
+Stoppe l'application courante sur l'appareil de présentation identifié par l'UUID `deviceUuid`. 
+
+## Objets
+
+### `Device`
+
+```typescript
+interface Device {
+    uuid: string    // UUID de l'appareil
+    name: string    // Nom de l'appareil
+    host: string    // Adresse IPv4 de l'appareil
+    port: number    // Port distant du service
+}
+```
