+## Setup
+
+To ensure that the input module's port is accessible, install the `udev` rule for it located in the `50-framework.rules` file.
+
+1. Copy it to your udev rules directory. On Ubuntu, this is located at `/etc/udev/rules.d/`
+2. Reload the rules with `sudo udevadm control --reload`
+
+You can debug issues using the `udevadm monitor --environment` command. Ensure that the device's `idVendor` and `idProduct` match when you plug in the device.
