I’ve watched this, looks good I don’t see what can be outdated, compare this video with documentation https://roots.io/docs/trellis/master/deployments/ and if you stuck somewhere try to find solution, on this forum, because it’s hard to point what exactly you do. A lot of errors was describe here so that can be very helpful.
Thanks. Yes I watched it a couple of times and was able to get up and running. Left a few comments on the video about what has changed in case anyone else is looking to get setup.
