setup_pi.md

First time setup

This is first time based on the UK raspbian images.

US setup

Usually the problem is the '|' character. if you type this and get '~' then you should update the keyboard layout:

sudo raspi-config

change keyboard layout

other -> generic 104 key

Not the International one.

It will ask you to pick from some UK options, choose other

Then get to the US options

Camera

sudo raspi-config

Interfacing options

SSH

# This makes it start on boot:
sudo systemctl enable ssh

# This starts it now:
sudo systemctl start ssh

Auth is password based by default.
