 For most parts, I followed the excellent [tutorial] on the Raspberry Pi website.

+## Set up Raspberry Pi
 
 1. On your usual computer, install an operating system on the microSD card. I used the [Raspberry Pi Imager](https://www.raspberrypi.com/documentation/computers/getting-started.html#install-an-operating-system). Make sure to configure the user account (username, password), WiFi settings, and host name.
 1. Insert microSD card into the Raspberry Pi. 
 1. Wait for the Raspberry Pi to boot.
 1. Connect using ssh using the user account configured in step 1: `ssh <user>@<host>.local`, for example: `mloning@raspberrypi.local`.
 1. On the Raspberry Pi, upgrade the system packages and restart: `sudo apt-get update && sudo apt-get upgrade --yes && sudo reboot`.
 
+A few useful commands:
+
+* `sudo shutdown -h now` to shut down. To start it again, re-connect the power cable.
+* `sudo reboot` to restart.

+1. To install Pi-hole, run: `curl -sSL https://install.pi-hole.net | bash`. In the [tutorial], the Raspberry Pi is connected via WiFi, with the `wlan0` interface being configured in the installation. If you can connect via an Ethernet cable, that's usually the preferred choice as it's more reliable, using `eth0` for the interface.

 To check if Pi-hole is running, try:
 
 * `pihole status`
 * `pihole -c` to open the console dashboard,
 * opening `http://<host>/admin/` (for example, `http://raspberrypi.local/admin/`) in the browser of your usual computer to login to the admin dashboard using the admin password.

+If you want to reconfigure Pi-hole later, run: `pihole -r` and select "reconfigure".

+## Configure Pi-hole as your network's DHCP provider
 
 My router did not allow me to set a DNS server, so I configured the DHCP provider instead.
 For other options, see the [tutorial].
