Okay I have had multiple people ask, so here are the useful websites that me and Beryl used to muddle our way through:
Using Pi-hole and Raspberry Pi (on the Raspberry Pi website, really good overview of what Pi-hole does)
Tumblr-archived Twitter thread about one household's experience with Pi-hole (this is what sold me on it. Also the tweets were published in 2022 and Pi-hole is actively being developed, so I think some of the teething problems he mentioned might have cleared up or are at least being addressed.)
Pi-hole website (gives broad strokes of the software and imho is not actually that helpful, however this proves that I am not making shit up)
Pi-hole documentation (read prerequisites carefully, you do NOT need the newest model of Raspberry Pi to run this thing!! You don't even need a Raspberry Pi at all, you can run it on a bunch of Linux systems however I'm very stupid when it comes to Linux and when my options are install and learn a whole ass new OS or spend $$ on a Raspberry Pi and hook it up to my TV with a wired mouse and keyboard I will unfortunately be spending money)
Privacy International's guide to setting up Pi-hole on a Raspberry Pi (bro this one saved our asses)
You guys can ask me questions if you want but I guarantee I will not know the answers bc I don't know shit about fuck, I just followed the directions and reaped the rewards. It did take us 2 hours to set up bc I'm bad at following directions (and it's kind of complicated if you've been out of the software game for a while like I have), and you do have to be sososo brave about fucking around with your internet provider's configuration. So make sure you eat before you do it!! However it has been so worth it for me so far, given that now all my devices at home are running faster and I'm not seeing any ads while web browsing. We will see what complaints my family comes up with, but I love it so far.
Also!! if you've never heard of Raspberry Pi, which I realize are not all of my followers are lost in the Silicon Valley sauce so you might not have, here's is their website and their page for using Raspberry Pi at home.
(And here is the Electronic Frontier Foundation, a nonprofit that fights for digital privacy, free speech, and innovation, if you, like me, were presented with cold hard data about your personal internet usage and suddenly realized that our internet is fully a dystopia. haha.)
