This is all I did on my Pi..
Downloaded Jess Lite from here.
https://www.raspberrypi.org/downloads/raspbian/
Used Win32DiskImager to write the image.
Booted the Pi.
logged in
passwd to change the default password.
sudo apt-get update to get the latest update list
sudo apt-get upgrade to get the latest updates
sudo apt-get upgrade-dist to get the OS update (won't be one at the moment..)
raspi-config once in this menu, I enabled SSH, so I can access the Pi over Kitty/Putty and do away with keyboard and screen from it.
Told my router to see it as 10.0.0.2 (my router is 10.0.0.1), for neatness
Rebooted Pi
Ran this..
curl -L https://install.pi-hole.net | bash
This installs Pi-Hole, I let it set itself as 10.0.0.2 static.
Now I went into my router settings and I set the
WAN DNS as 10.0.0.2 (primary), 8.8.8.8 (secondary).
I wouldn't set the DHCP DNS as the Pi-Hole, might get some odd things happening.
