Welcome to the group.
Installation or upgrades do not need any compile skills, but at minimum you need to know how to download one of Randys images, and if I remember correctly you have to unzip the downloaded file, and then you need to use the Raspberry Pi imager software to burn that image onto an SD card.
So even for the beginner there are a few things you need to know, but fear not, you can always ask google, or an AI, or this group.
The installation is fully automated, and upgrades happen over Wifi/Ethernet without technical skills needed.
No need to compile anything. But installation and setup does require some basic SD card and image handling skills, as well as maybe some basics on the Raspberry operating system.
