0. For a clean OS (Like Ubuntu 18) you need to install and configure docker (after adding user in the docker group a relogin is needed), as well as git and make.
2. Determine the target hardware configuration (platform). If you are using an analog VGA video capture device, choose `v0-vga`. If you want to use HDMI with Auvidea B101, choose `v0-hdmi`. Other options are for specialized Pi-KVM boards (WIP).
3. Create config file `config.mk` for the target system. You must specify the path to the SD card on your local computer (this will be used to format and install the system) and the version of your Raspberry Pi and platform. You can change other parameters as you wish:
```Makefile
$ cat config.mk
[user@localhost ~]$ cat config.mk
# rpi3 for any Raspberry Pi 3, rpi2 for version 2.
BOARD = rpi3

5. Put SD card into card reader and install OS:
```shell
$ make install

```
6. After installation remove the SD card and insert it into your Raspberry Pi. Turn on the power. Raspberry Pi will try to get ad IP address using DHCP on your LAN. Congratulations! Your Pi-KVM will be available via SSH (`ssh root@<addr>`) and HTTPS (try to open it in a browser at `https://<addr>`). For HTTPS a self-signed certificate is used by default.

Be sure to check the bottom of this README for [Tips](#tips) and [Troubleshooting](#troubleshooting)!
8. Now you need to flash Arduino. This can be done using your RPi. **Before starting this operation, disconnect the RESET wire from Arduino, otherwise the firmware will not be uploaded. Connect the Arduino and RPi with a suitable USB cable.** Log in to RPi and upload the firmware. Then connect RESET wire back, disconnect USB and reboot RPi.
