+Create a ``Client`` with a server URL, a transport, and a ``BearerAuthMiddleware``. With an API key from App Store Connect, ``APIKeyTokenProvider`` signs the JSON Web Tokens (JWT) the API requires, and renews them before they expire:
 
 ```swift
 import ASConnectService
 import OpenAPIURLSession
 
-let client = Client(
-    serverURL: try Servers.Server1.url(),
-    transport: URLSessionTransport(),
-    middlewares: [
-        BearerAuthMiddleware(token: yourJWTToken)
-    ]
-)
-```
-
-Tokens expire after 20 minutes at most. For longer-lived clients, use ``APIKeyTokenProvider``, which signs new ones with your API key as needed:
-
-```swift
 let tokenProvider = try APIKeyTokenProvider(
     issuerID: yourIssuerID,
     keyID: yourKeyID,
     privateKey: yourP8FileContents
 )
 
-BearerAuthMiddleware {
-    try await tokenProvider.token()
-}
+let client = Client(
+    serverURL: try Servers.Server1.url(),
+    transport: URLSessionTransport(),
+    middlewares: [
+        BearerAuthMiddleware { try await tokenProvider.token() }
+    ]
+)
+```
+
+To use a token you signed yourself, pass it directly. It expires after 20 minutes at most:
+
+```swift
+BearerAuthMiddleware(token: yourJWTToken)
 ```
