+
+-   Pair Light Example to E2
+
+    Since Fabric-Bridge also functions as a Matter server, running it alongside
+    the Light Example app on the same machine would cause conflicts. Therefore,
+    you need to run the Matter Light Example app on a separate physical machine
+    from the one hosting Fabric-Sync.
+
+    ```sh
+    > app add-device 3 <setup-pin-code> <device-remote-ip> <device-remote-port>
+    ```
+
+    After the device is successfully added, you will observe the following
+    message on E2 with the newly assigned Node ID:
+
+    ```sh
+    > New device with Node ID: 0x3 has been successfully added.
+    ```
+
+    Additionally, you should also get notified when a new device is added to E2
+    from the E1:
+
+    ```sh
+    > A new device is added on Endpoint 3.
+    ```
+
+-   Synchronize Light Example to E1
+
+    After the Light Example is successfully paired in E2, we can start to
+    synchronize the light device to E1 using the new assigned dynamic endpointid
+    on Ecosystem 2.
+
+    ```sh
+    > app sync-device <endpointid>
     ```
