It was (pretty much) just dot files and curated software, although I think that description downplays the value of having a perfectly tuned system out of the box - like saying a log cabin is just a bunch of sticks. The assembly matters and the end result is something greater than the sum of its parts.

That aside, the latest release (Quattro) has also added a bunch of bespoke software (technically quickshell configuration, if you don't want to call it software) which has added a new layer of polish. For my taste it has been a real joy to use and a lot of fun to explore and play around with. Could be worth checking out if you haven't looked in a while!
