 Qiskit Serverless has a client-server architecture,
 which means that in order to interact with computational
 resources, you need to have the client library
-installed on your machine and configured to communicate with the provider.
+installed on your machine and configured to communicate with the server.
 
 To install the client library, run:
 
 .. code-block::
 
-        pip install qiskit_serverless
+        pip install qiskit-serverless
 
 
 Next, we need to configure the client to communicate with the provider.
-This can be done through the `BaseProvider` configuration.
+This can be done through the `ServerlessClient` configuration.
 
-Before we can configure the client and provider,
-we need to know two things: the `username/password`
-(authentication details) and the `host` of our gateway server.
+Before we can configure the client, we need to know two things: 
+the `token` (authentication details) and the `host` of our gateway server.
 
 If you are using the local docker compose setup,
-your username and password would be `user` and `password123`,
-respectively, and the host would be `http://gateway:8000`.
+your token would be `awesome_token` and the host would 
+be `http://gateway:8000`.
 
-If you are using a cloud deployment, your cloud administrator
-will provide you with the details of the host and authentication.
+If you are using `IBMServerlessClient`, you only need to pass the `tokne`.

 Once you have all the necessary information,
 you can start configuring the client:
 
 .. code-block::
 
-		from qiskit_serverless import QiskitServerless, ServerlessProvider
+		from qiskit_serverless import ServerlessClient
 
-		provider = ServerlessProvider(
-			username="<USERNAME>",
-			password="<PASSWORD>",
+		client = ServerlessClient(
+			token="<TOKEN>"
 			host="<HOST>",
 		)
 
-		client = QiskitServerless(provider)
-
-With this configuration in place, you can run your programs
-against the provider.
+With this configuration in place, you can run your Qiskit Functions.
