+### Prequisites
+
+* DietPi
+* At least kernel 4.14 (Mainline is prefered)
+* The HM-MOD-RPI-PCB and the RPI-RF-MOD are only working on supported platforms
+
+### Installation
+0. Create full backup of your SD card
+1. Add the public key of the repository
+   ```bash
+   wget -q -O - https://apt.pivccu.de/piVCCU/public.key | sudo tee /usr/share/keyrings/pivccu.asc
+   ```
+
+2. Add the package repository
+   ```bash
+   echo "deb [signed-by=/usr/share/keyrings/pivccu.asc] https://apt.pivccu.de/piVCCU stable main" | sudo tee /etc/apt/sources.list.d/pivccu.list
+   sudo apt update
+   ```
+   Instead of `stable` you can also use the `testing` tree, but be aware testing sometimes means not that stable.
+
+3. Install the matching kernel headers
+   ```bash
+   sudo apt install build-essential bison flex libssl-dev
+   sudo apt install `dpkg --get-selections | grep 'linux-image-' | grep '\sinstall' | sed -e 's/linux-image-\([a-z0-9-]\+\).*/linux-headers-\1/'`
+   ```
+
+4. If you are using a HB-RF-ETH, install the neccessary support package
+   ```bash
+   sudo apt install hb-rf-eth
+   ```
+
+5. Install the neccessary device tree patches (You can skip this step, if you do not use the HM-MOD-RPI-PCB or RPI-RF-MOD on GPIO header, for the HB-RF-USB(-2) and HB-RF-ETH this step is not neccessary)
+   ```bash
+   sudo ln -sf /boot/dietpiEnv.txt /boot/armbianEnv.txt
+   sudo apt install pivccu-devicetree-armbian device-tree-compiler
+   ```
+
+6. Install the neccessary kernel modules
+   ```bash
+   sudo apt install pivccu-modules-dkms
+   ```
+
+7. Add network bridge (if you are using wifi please refer to the debian documentation how to configure the network and the bridge)
+  * Verify, that *eth0* is the name of your primary network interface:
+     ```bash
+     sudo ip link show | cut -d' ' -f2 | cut -d: -f1 | grep -e '^e.*'
+     ```
+
+  * Update your config. (Replace *eth0* if necessary)
+     ```bash
+     sudo apt install bridge-utils
+     sudo bash -c 'cat << EOT > /etc/network/interfaces.d/pivccu
+     iface eth0 inet manual
+
+     auto br0
+     iface br0 inet dhcp
+       bridge_ports eth0
+     EOT'
+     ```
+  * You can use an static IP address, too. In that case use instead:
+     ```bash
+     sudo apt install bridge-utils
+     sudo bash -c 'cat << EOT > /etc/network/interfaces.d/pivccu
+     iface eth0 inet manual
+
+     auto br0
+     iface br0 inet static
+       bridge_ports eth0
+       address <address>
+       netmask <netmask>
+       gateway <gateway>
+       dns-nameservers <dns1> <dns2>
+     EOT'
+     ```
+  * To use Wireless LAN, please take a look [here](wlan.md)
+
+8. Reboot the system
+   ```bash
+   sudo reboot
+   ```
+
+9. Install CCU container
+   ```bash
+   sudo apt install pivccu3
+   ```
+
+10. Start using your new virtualized CCU, you can get the IP of the container using
+   ```bash
+   sudo pivccu-info
+   ```
