I am putting together a series of Getting Started manuals for FujiNet. The first one is for Atari 8-bit systems.
In each case, the manual is typeset like the owners manuals for each target system.
PDF attached.
The source can be pulled via GitHub, and can be adapted for other languages, in fact I hope so.
