+## Using the Atem sample bundle
+
+The Atem sample bundle in `samples/atem` shows how to listen to commands.
+
+### Prerequisites
+
+You will need a working `nodecg-io` installation. If you have non yet take a
+look at [installation guide](../getting_started/install.md). You may need to
+install this bundle, so take a look at the
+[“Try an included sample”](../getting_started/try_example_bundle.md)-Guide. It
+will also tell you how to log in and how to use the GUI.
+
+
+### Configure the Atem sample bundle
+
+1. In NodeCG, create a new atem service instance.
+2. Enter the address and optional a port of the Atem server:
+
+    ```json
+    {
+        "address": "0.0.0.0"
+    }
+    ```
+
+    or
+
+    ```json
+    {
+        "address": "0.0.0.0",
+        "port": 9910
+    }
+    ```
+
+    After entering it, click save.
+
+3. Set the sample's (`atem`) dependency to be the newly created
+   service instance (of type `atem`).
+4. Now all commands sended through the atem protocol should be logged in the console.
