RaspberryPi3
From charlesreid1
This page has some notes on the Raspberry Pi 3. Note that it's basically exactly the same as the Raspberry Pi 2.
Installing
Image
I utilized the image ubuntu-16.04-preinstalled-server-armhf+raspi3.img from this link: https://wiki.ubuntu.com/ARM/RaspberryPi
Booting
Everything's pretty straightforward, once you've written the Pi image file onto the SD card, you plug it in and you fire it up.
Running
Startup
Anything you want to run on startup should go in /etc/rc.local
If you want to start wifi on boot, you can add the wireless network name and credentials to the /etc/wpa_supplicant/wpa_supplicant.conf
