+# HsMouse
+Experimental control software for robotics, tested on Raspberry Pi 5.
+
+## System Configuration:
+To configure the system, the files in the `sysconf` directory must be
+installed:
+
+1. Copy the UDEV `*.rule` files into `/etc/udev/rules.d`.
+2. Copy `config.txt` to `/boot`.
+3. Reboot the Raspberry Pi for the changes to take effect.
+
+## GPIO and PWM Access Without Root:
+To enable GPIO and PWM access without root privileges on the Raspberry Pi 5,
+follow these steps:
+
+1. Create two new user groups: `gpiod` and `pwm`.
+2. Add your user to both groups.
+3. The UDEV rules installed previously will grant the `gpiod` and `pwm` user
+groups permission to access the respective subsystems.
+
+This configuration ensures that GPIO and PWM operations can be performed
+without needing root access.
+
+## Build Instructions:
+1. Install [`stack`](https://docs.haskellstack.org/en/stable/). It’s
+recommended to use [`ghcup`](https://www.haskell.org/ghcup/) for installation.
+2. Run `stack build` to compile the libraries and executables.
+
+> Note: You may need to install system dependencies on your host first (e.g.,
+> `libgpiod`, etc.)
