 I wrote this to control the "hardware" on KW1FOX-1 tower.
 
 its.. not really intended for use anywhere else but, if anything inspires you go ahead and grab it!
-Just some simple python.
 
-# Install
+## Install
 
 ```shell
 sudo git clone https://git.kitsunehosting.net/Kenwood/towerd.git /opt/towerd
 cd /opt/towerd
-sudo python3 -m venv venv
-sudo venv/bin/pip install -r requirements.txt
+cargo build --release
 sudo cp systemd/towerd.service /etc/systemd/system/
 sudo systemctl daemon-reload
 sudo systemctl enable --now towerd
-```
\ No newline at end of file

+
+## Usage
+
+```shell
+./target/release/towerd --verbose
+
+# systemd
