+#### 🎧 Spotify API
+
+To access Spotify metadata, the project now uses the official [Spotify Web API](https://developer.spotify.com/documentation/web-api/). This requires creating a developer application and retrieving a client ID and client secret.
+
+Follow the [official getting started guide](https://developer.spotify.com/documentation/web-api/tutorials/getting-started#request-an-access-token) to:
+
+1. Create a Spotify developer app.
+2. Copy your **Client ID** and **Client Secret**.
+
+Create a file named `credentials.json` in the `server/` directory with the following structure:
+
+```json
+{
+  "client_id": "your-client-id",
+  "client_secret": "your-client-secret"
+}
+```
+The application will automatically read this file to fetch and cache access tokens. If the token is expired or missing, a new one will be requested.
