I set one up. My IT skills begin and end with being a millennial that had to troubleshoot what I wanted to get to work before App stores.
You'll be fine in general searching "Pihole setup (insert OS here)". Some minor troubleshooting was necessary in my case, could be an ID10T issue though.
Yes setting up a Pi-Hole should be pretty doable for someone like you. I can't recomend a specific tutorial off the top of my head, but there should be plenty to find.
You mainly need a pi running raspbian or a pc running some debian based distro.
I do wonder how long it's going to take for these device manufacturers to get wise and start hard coding their own host file on these devices with the addresses they use.
Firebog.net Ticked lists as a collective, over 10^6 domains long now. Firebog have lists organised by how likely it is to impact general browsing, ticked being least likely (basically do you want to be black listing or white listing).
Thank you. And good advice about over-doing it. I've had people complain about "the internet being broken" on my wifi because of an overly-restrictive pi hole.
