Can someone please explain how exactly does this work? So I have an ubuntu system. Is it ok to just install it in my local system alone and use it? Or should I be doing something to connect to a modem or something? I currently use my phone as the hotspot for my computer. If I install it say in a remote server in digital ocean, how can I use my phone/computer to use pi hole? Still a noob when it comes to networking so any help is appreciated thanks :)

Not an expert with PiHole other than having set-up one myself not so long ago. It is a DNS server. Basically whatever you put into DNS Server list on your device (some host on local network, some host with public IP) - your device will send DNS queries to THAT host. More often than not, you will configure your router to hand out your local devices these DNS servers via DHCP. So that answers the question: you can host it on local network or use remote server (given you have public IP and can open port 53/UDP). If you don't have firewall there, you will probably be configuring host local firewall to allow using DNS from hosts@home. It may get complicated if you have a dynamic address for your home router.

You can install it on any device you want. Just make sure you point to it as your DNS server. My setup: 2x Raspberry Pi running Pi-hole 1x OpenWRT running DHCP DHCP answers with DNS servers rpi1 and rpi2 IP addresses. Does this make sense?
