+## Requirements
+
+-   [OBS Studio](https://obsproject.com/)
+-   [OBS Python SDK for Websocket v5](https://github.com/aatikturk/obsws-python)
+
+## About
+
+Perhaps you have a streaming setup but you want to control OBS and Voicemeeter from a remote location with python installed.
+With the vban-cmd and obsws-python packages you may sync a distant Voicemeeter with a distant OBS over LAN.
+
+## Configure
+
+This script assumes the following:
+
+-   OBS Connection info in a valid `config.toml`:
+
+    ```toml
+    [connection]
+    host = "gamepc.local"
+    port = 4455
+    password = "mystrongpass"
+    ```
+
+-   VBAN Connection info in a valid `vban.toml`:
+
+    ```toml
+    [connection]
+    ip = "gamepc.local"
+    port = 6980
+    streamname = "Command1"
+    ```
+
+-   Both configs should be placed next to `__main__.py`.
+
+-   Four OBS scenes named "START", "BRB", "END" and "LIVE".
+
+## Use
+
+Make sure you have established a working connection to OBS and the remote Voicemeeter.
+
+Run the script, change OBS scenes and watch Voicemeeter parameters change.
+
+Pressing `<Enter>` will exit.
+
+## Notes
+
+This script can be run from a Linux host since the vban-cmd interface relies on UDP packets and obsws-python runs over websockets.
+
+You could for example, set this up to run in the background on a home server such as a Raspberry Pi.
+
+It requires Python 3.10+.
