 ## [Raspberry Pi 4][2]
 
+Install Raspberry Pi OS.
+
+Switch to root user. Default password is blank for Raspberry Pi OS.
+
+```shell
+sudo su root
+```
+
+Set root password so that you can log into Proxmox web GUI.
+
+```shell
+passwd
+```
+
+Add an `/etc/hosts` entry for your IP address
+
+Please make sure that your machine's hostname is resolvable via `/etc/hosts`, i.e. you need an entry in `/etc/hosts` which assigns an address to its hostname.
+
+Make sure that you have configured one of the following addresses in `/etc/hosts` for your hostname:
+
+1 IPv4 or
+1 IPv6 or
+1 IPv4 and 1 IPv6
+Note: This also means removing the address 127.0.1.1 that might be present as default.
+
+For instance, if your IP address is 192.168.15.77, and your hostname prox4m1, then your /etc/hosts file could look like:
+
+```
+127.0.0.1       localhost.localdomain localhost
+192.168.15.77   prox4m1.proxmox.com prox4m1
+
+# The following lines are desirable for IPv6 capable hosts
+
+::1     localhost ip6-localhost ip6-loopback
+ff02::1 ip6-allnodes
+ff02::2 ip6-allrouters
+```
+
+You can test if your setup is ok using the hostname command:
+
+```shell
+hostname --ip-address
+```
+
+```shell
+192.168.15.77 # should return your IP address here
+```
+
+### Install Proxmox VE
+
+##### Add the Proxmox VE repository:
+
+```shell
+echo 'deb [arch=arm64] https://mirrors.apqa.cn/proxmox/debian/pve bookworm port'>/etc/apt/sources.list.d/pveport.list
+```
+
+Add the Proxmox VE repository key:
+
+```shell
+curl -L https://mirrors.apqa.cn/proxmox/debian/pveport.gpg -o /etc/apt/trusted.gpg.d/pveport.gpg 
+```
+
+Update your repository and system by running:
+
+```shell
+apt update && apt full-upgrade
+```
+
+Install Proxmox VE packages
+Install the ifupdown2 packages
+
+```shell
+apt install ifupdown2
+```
+
+Install the Proxmox VE packages
+
+```shell
+apt install proxmox-ve postfix open-iscsi
+```
+
+Configure packages which require user input on installation according to your needs (e.g. Samba asking about WINS/DHCP support). If you have a mail server in your network, you should configure postfix as a satellite system, your existing mail server will then be the relay host which will route the emails sent by the Proxmox server to their final recipient.
+
+If you don't know what to enter here, choose local only and leave the system name as is.
+
+Finally, you can connect to the admin web interface (https://youripaddress:8006).
