+## Using the GameTTS sample bundle
+
+The GameTTS example bundle in `samples/gametts` demonstrates the ability
+to play a tts generated audio in a graphic. Here is a guide
+to how to get it working.
+
+Note that GameTTS only supports german voices.
+
+### 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.
+
+**You also need:**
+
+-   a GameTTS Server Instance
+
+
+!!! NOTE
+
+    GameTTS can be found at https://github.com/lexkoro/GameTTS.
+    A docker image of GameTTS is available on docker hub at `henrikhansen/gametts:latest`.
+
+    Here's an example docker compose file to get it working:
+
+    ```yaml
+    version: '3'
+
+    services:
+      gametts:
+        image: henrikhansen/gametts:latest
+        restart: always
+        ports:
+          - 5000:5000
+        container_name: gametts
+        volumes:
+          - ./gametts:/usr/src/app/GameTTS/vits/model/
+    ```
+
+### Configure the GameTTS sample bundle
+
+1. In NodeCG, create a new gametts service instance.
+
+2. Enter your host information like this
+
+    ```json
+    {
+        "host": "example.com:12345",
+        "useHttps": false
+    }
+    ```
+
+    After entering it, click save.
+
+3. Set the sample's (`gametts`) dependency to be the newly created service
+   instance (of type `gametts`).
+
+4. Open the GameTTS sample bundle graphic:
+
+    You should hear "Hallo aus nodecg-io!" using a random TTS voice.
