There is literally a PDF titled "fastiron-*-l3guide.pdf / Layer 3 Routing Configuration Guide." It starts with ARP and ends with Multi-VRF. The command reference is just one among many documents.The manuals from the Rucksu/Commscope site or pacakged in Fohdeesha's ZIP assume that you have a passing familiarity with the concepts. The manufacturer's documentation is not going to have a full "here's how you go form first start to routed VLAN" example; it's mostly a command reference that will have specific, basic examples of a given command.
Honestly a lot of that is out of my comfort zone but it serves as a great starting point. The documents provide a good starting foundation. Isn't this what "homelab" is all about? Self learning and initiative? If someone wants to be spoonfed they can get a support contract and ask the vendor directly. Otherwise it's slogging through threads like this one.
Sorry for sounding like an asshole.
