The first versions of Alt Linux for Star64. The startup process is similar to Armbian (you do not need to re-run the loader once, if it has already been done before). Launching Alt linux - download the image, unpack it, burn it to an SD card, insert it into Star64 and turn on the power, the system starts automatically. As part of the images with DE (ICEWM XFCE MATE etc), there is a working Firefox browser, with minimal settings, you can even watch YouTube, if you set the desktop resolution to no more than 1280x720, you can even use the full screen, this is not ideal, but good enough for the primary version. 
For the “builder” image (this is an image that can be used to build packages or the Altlinux system itself) and the minimum “jeos” image is the primary user “root” and the password “altlinux”.
