+### Install via Swift Package file
+
+Add the dependency to your existing `Package.swift` file.
+```Swift
+dependencies: [
+    .package(url: "https://tidal-music.github.io/tidal-sdk-ios", from: "<VERSION>"))
+]
+```
+
+### Install via Swift Package Manager with Xcode
+
+1. Select `"File » Add Packages Dependencies..."` and enter the repository URL `https://github.com/tidal-music/tidal-sdk-ios` into the search bar (top right).
+2. Set the Dependency Rule to `"Up to next major"`, and the version number to that you want. 
+3. When `"Choose Package Products for tidal-sdk-ios"` appears, make sure to at least add `TidalAPI` and `Auth` to your target.
+
+### Fetching a TIDAL album example
+
+The TidalAPI depends on the [Auth](https://github.com/tidal-music/tidal-sdk-ios/blob/main/auth/README.md) module for authentication and providing a `CredentialsProvider`. For detailed instructions on how to set it up, please refer to its guide.
+
+> [!NOTE] 
+Different TIDAL API endpoints require different level of authentication. For endpoints where user data is accessed, a user authentication is required following the [Authorization Code Flow](https://github.com/tidal-music/tidal-sdk-ios/tree/main/Sources/Auth#authorization-code-flow-user-login). For others, such as catalog access, [Client Credentials Flow](https://github.com/tidal-music/tidal-sdk-ios/tree/main/Sources/Auth#client-credentials) is enough. 
+
+Here's how to setup the TidalAPI with `Client Credientials` flow and fetch a TIDAL album:
+
+1. Initialise and configure `TidalAuth`.
+
+```Swift
+import Auth
+import TidalAPI
+
+let auth = TidalAuth.shared
+auth.config(
+    config: AuthConfig(
+        clientId: "YOUR_CLIENT_ID",
+        clientSecret: "YOUR_CLIENT_SECRET",
+        credentialsKey: "YOUR_CREDENTIALS_KEY"
+    )
+)
+```
+
+2. Connect the `CredentialsProvider` to `OpenAPIClientAPI`.
+
+```Swift
+let credentialsProvider: CredentialsProvider = auth
+OpenAPIClientAPI.credentialsProvider = credentialsProvider
+```
+
+3. Fetch an album.
+
+```Swift
+let result = try await AlbumsAPITidal.getAlbumById(id: "ALBUM_ID", countryCode: "COUNTRY_CODE")
+print(result)
+
+/*
+AlbumsSingleDataDocument(
+	data: Optional(
+		TidalAPI.AlbumsResource(
+			attributes: Optional(
+				TidalAPI.AlbumsAttributes(
+					title: "Gold", 
+					barcodeId: "00602435565811", 
+					numberOfVolumes: 1, 
+					numberOfItems: 16, 
+					duration: "PT57M31S", 
+					explicit: true, 
+					releaseDate: Optional(2022-08-12 00:00:00 +0000),
+					...
+			)
+		)
+	)
+)
+*/
+```
