+7. A Clio server needs to access a `rippled` server to run succesfully. To enable communication between the servers, the config files of Clio and `rippled` need to share the following information. Run `./clio_server config.json` and update the config files as described:
 
-        systemctl status rippled.service
+    1. Update the Clio server's config file with the following information:
+        
+        * The IP of `rippled` server.
+        * The port on which `rippled` is accepting unencrypted WebSocket connections.
+        * The port on which `rippled` is handling gRPC requests.
 
-    The `rippled` service should start automatically. If not, you can start it manually:
+                    "etl_sources":
+                    [
+                        {
+                            "ip":"127.0.0.1",
+                            "ws_port":"6006",
+                            "grpc_port":"50051"
+                        }
+                    ]
 
-        sudo systemctl start rippled.service
+        **Note** You can use multiple `rippled` servers as a data source by add more entries to the `etl_sources` section. Clio will load balance requests across the servers specified in the list. As long as one `rippled` server is up and synced, Clio will continue to extract validated ledgers.
 
-    To configure it to start automatically on boot:
+    2. Update the `rippled` server's config file with the following information:
+        
+        * Open a port to accept unencrypted websocket connections. 
+        * Open a port to handle gRPC requests and specify the IP(s) of Clio server(s) in the `secure_gateway` entry.
 
-        sudo systemctl enable rippled.service
+                "server":{
+                    "ip":"0.0.0.0",
+                    "port":51233
+                }
 
-8. Optional: allow `rippled` to bind to privileged ports.
 
-    This allows you to serve incoming API requests on port 80 or 443. (If you want to do so, you must also update the config file's port settings.)
