I bought a Raspberry Pi 3. It has 1G of RAM and a 4 core processor.

I copied a file onto a micro SD card.

After the Raspberry Pi booted up, I used to open a console. I logged in as pi. I ran sudo passwd and gave my new root password twice. I ran su and was logged in as root.

I ran raspi-config to set up the keyboard.

I added four lines to /etc/dhcpcd.conf so that I would have a fixed ip address. interface eth0
static ip_address=nnn.nnn.nnn.nnn/24
static routers=nnn.nnn.nnn.1
static domain_name_servers=nnn.nnn.nnn.50 I edited the /etc/hostname file. Be sure to give the fully qualified hostname, i.e. .. Example: "pi3.nthist.com"

I created a new user. ( adduser nthist )

I put the new user into several groups. ( usermod -a -G audio,bluetooth,netdev,video nthist )
