One nitpick is that while the site looks clean, and there seems to be some good amount of documentation, i think there was a lost opportunity for a simple, yet more universal description of *what this is*! I mean, i get that this descends from FreeNAS and TrueNAS CORE...but why could they not add a small, single line of text that also helps explain it to other folks who don't know fully what the means? Here is a crappy but at least slightly more descriptive option:
"FreeCORE is an operating system and associated software for your network attached storage (NAS) needs. FreeCORE descends from FreeNAS and TrueNAS® CORE, and builds on FreeBSD and OpenZFS..."
I'm not going to win the Pulitzer prize any time soon, i get that. But at least most folks will get a little more of the gist of what this FreeCore thing is or could help them. I'm only making this suggestion because i want more folks to participate and enjoy free and open source software. I'm not expecting someone's grandparents to understand this, but i betcha other folks who for example might be migrating from Windows NAS-like offerings might have an interest...so making the intro at least a tiny more descriptive helps.
Again, even with my comments, i do wish the team well, and only want them to succeed. So please take my comments as merely a suggestion for improving things for all to benefit. In fact I'll be playing around with this to set it up and test on my homelab.
