# Building PiKVM OS
The assembly of PiKVM OS is carried out using a special build environment.
Here the minimum required for its use, imposed on the build machine:
* kernel >= 5.8
* glibc >= 2.33
* docker >= 19.03.13
* git
Docker must work in privileged mode.
1. When starting with a clean OS you need to install and configure Docker. An example for Ubuntu:
```console
[user@localhost ~]$ sudo apt-get install git make curl binutils -y
[user@localhost ~]$ sudo apt-get install docker.io
[user@localhost ~]$ sudo usermod -aG docker $USER
```
Re-login to apply the changes.
2. Checkout the build environment:
```console
[user@localhost ~]$ git clone --depth=1 https://github.com/pikvm/os
[user@localhost ~]$ cd os
```
3. Determine the target board and platform:
* Choose the board:
* `BOARD=rpi4` for Raspberry Pi 4.
* `BOARD=zero2w`
* `BOARD=rpi3`
* `BOARD=rpi2`
* Choose the platform:
* `PLATFORM=v4mini-hdmi` for PiKVM V4 Mini.
* `PLATFORM=v4plus-hdmi` for PiKVM V4 Plus.
* `PLATFORM=v3-hdmi` for RPi4 and PiKVM V3 HAT.
* `PLATFORM=v2-hdmi` for RPi3a+/RPi4 or Zero2W with HDMI-CSI bridge.
* `PLATFORM=v2-hdmiusb` for RPi4 with HDMI-USB dongle.
* `PLATFORM=v0-hdmi` for RPi2 or 3b+ with HDMI-CSI bridge and Arduino HID.
* `PLATFORM=v0-hdmiusb` for RPi2 or 3b+ with HDMI-USB dongle and Arduino HID.
4. Create the build config file `config.mk` for the target system and and the `BOARD` and `PLATFORM` variables.
You can also set some other parameters as you wish (see below).
Please note: if your password contains the # character, you must escape it using a backslash like `ROOT_PASSWD = pass\#word`.
```bash
# Base board
BOARD = rpi4
# Hardware configuration
PLATFORM = v2-hdmi
# Target hostname
HOSTNAME = pikvm
# ru_RU, etc. UTF-8 only
LOCALE = en_US
# See /usr/share/zoneinfo
TIMEZONE = Europe/Nicosia
# For SSH root user
ROOT_PASSWD = rootpass
# Web UI credentials: user=admin, password=adminpass
WEBUI_ADMIN_PASSWD = adminpass
# IPMI credentials: user=admin, password=adminpass
IPMI_ADMIN_PASSWD = adminpass
```
4. Build the OS. It may take about one hour depending on the Internet connection:
```console
[user@localhost os]$ make os
```
!!! tip
If you get an error about failing to retrieving a file, please edit the Makefile and remove `de3.` from the repo URL.
5. Create an image. It will be stored in the `images` directory as a file with `*.img` extension:
```console
[user@localhost os]$ make image
```
6. [Flash the result image to SD card](flashing_os.md#flashing-the-image).
