- Get a Raspberry Pi (I'm using Zero W, but any will do)
- Download Raspbian Jessie (becareful, not Stretch as the Trezar Wallet won't work there) 2a. Lite version, if you don't plan on using Desktop and want to save some system resources
- Install on your SD card: https://www.raspberrypi.org/documentation/installation/installing-images/README.md 4a. Either prepare a monitor+keyboard 4b. Create empty file with name 'ssh' in boot partition and setup WiFi if you need to: https://thepihut.com/blogs/raspberry-pi-tutorials/83502916-how-to-setup-wifi-on-raspbian-jessie-lite
(Optionally: Update hostname https://thepihut.com/blogs/raspberry-pi-tutorials/19668676-renaming-your-raspberry-pi-the-hostname)
- Put it all together, insert prepared SD card into your RPi and power on. Wait for the raspbian initialization do it's magic first.
- Login through ssh (default raspbian username is 'pi' and password 'raspberry') or locally
- Run instalation command:
wget -q -O- https://raw.githubusercontent.com/mkapusnik/trezarpi/master/install | bash
