 ## Hardware
 
-This program is strongly customized to my needs, and my DIY exposure unit has **two buttons** and **one switch** to interact with the software (and a power switch FWIW). Also, a **16x2 display** (maybe 20x4 or others do also work, but these are not tested) can show information to the user.

 A **relais** is used for switching all the LEDs.

-## Installation
+## Software installation
 
 To install this software on your Pi Pico, first clone the repository with `git clone --recurse-submodules` to populate the submodules also (some libraries are included as submodules). Then use [Thonny](https://thonny.org/), open all the files present in this repository and then save them onto a [Raspberry Pi Pico](https://www.raspberrypi.com/products/raspberry-pi-pico/) (or [Pico 2](https://www.raspberrypi.com/products/raspberry-pi-pico-2/), but it's not tested on this platform yet) running [MicroPython](https://micropython.org/). Then, given you followed above wiring, it should just be running! Then you can jump over the configuration section.

 - If your display doesn't work properly - the first issue might be a wrong i2c address. To find the address of your display, just follow some of the tutorials on the internet on scanning for i2c devices (e.g. [here](https://randomnerdtutorials.com/raspberry-pi-pico-i2c-scanner-micropython/)).
 
+- The most basic configuration changes can be made directly from the device, without the need of connecting it to a PC, essentially making it a kind-of standalone device once flashed!
