+# ``Client``
+
+The API client for performing HTTP operations against the App Store Connect API.
+
+## Overview
+
+The ``Client`` struct is the main entry point for interacting with the App Store Connect API. It conforms to ``APIProtocol`` and provides concrete implementations for all available API operations.
+
+### Creating a Client
+
+Create a ``Client`` by providing a server URL, a transport, and optionally a list of middlewares for authentication or request customization.
+
+```swift
+import ASConnectService
+import OpenAPIURLSession
+
+let client = Client(
+    serverURL: try Servers.server1(),
+    transport: URLSessionTransport(),
+    middlewares: [
+        BearerAuthMiddleware(token: yourJWTToken)
+    ]
+)
+```
+
+### Making API Calls
+
+Each method on the ``Client`` corresponds to an HTTP endpoint defined in the App Store Connect API OpenAPI specification. Methods accept an `Input` value and return an `Output` value representing the response.
+
+```swift
+let response = try await client.appsGetCollection(.init())
+```

+# ``Servers``
+
+Server URLs defined in the OpenAPI document.
+
+## Overview
+
+The ``Servers`` namespace provides access to the base URLs defined in the App Store Connect API OpenAPI specification. Use these URLs when creating a ``Client`` instance.
+
+```swift
+let client = Client(
+    serverURL: try Servers.Server1.url(),
+    transport: URLSessionTransport(),
+    middlewares: [
+        BearerAuthMiddleware(token: yourJWTToken)
