Looking for an ASL 3 tutorial

Hi all
I’m new to AllStarLink and I’m looking for a recent tutorial that goes through configuring a new ASL 3 node on a Raspberry Pi. I’ve searched YouTube and everything seems to be covering either HamVOIP or an old version of ASL.

I want to be able to do more with ASL than simply create a local node: such as use asl_zello_bridge to allow me to get into my local - un-networked - repeater when I am out of range; so I need more than just an installation video.

Way back (c2005), I set up an Asterisk PBX in the house, but Asterisk has evolved a lot since then, and in any case, I’ve forgotten 99% of what I learned then.

Thanks

Best thing right now is the current ASL 3 documentation at https://allstarlink.github.io/.
