The rules as published as free HTML pages divided into an introduction and three main sections (using an unfortunate black-on-blue color scheme). A fourth section presents a very high-level map of the world of Godshome (three normal continents, one special continent, about fifteen cities).
The three HTML sections include:
Character Sheet (simple, one page)
The History of Godshome (primarily, campaign setting)
