I think it’s best described as a project aimed at making it as easy as possible for someone new to Linux and SDRs to run either a live Linux distro or install Linux and quickly be up and running with not only popular well know easily installed SDR software but also harder to install and/or compile software. Combined with YouTube videos it ensures everyone’s on the same page and able to follow along. https://www.youtube.com/channel/UC9U2kaqhE716J2WNSTcOghg
