Adventurer, Conqueror, King System SRD in HTML
I have two HTML versions of the ACKS SRD available:
Everything in one file, which makes searching it easy, but it's slower to load.
Divided up by Chapters, which makes it a little faster to load.
Both of these are based on the Markdown SRD, which was forked from the Text SRD. The chapters version is produced directly from the Markdown SRD. The one file version is produced from a lightly edited version of the Markdown SRD processed through pandoc.
Producing PDFs from the Markdown files via pandoc would be difficult, as there are several tables that are too wide to fit on a page. Go buy the ACKS pdf if you want an nice looking PDF.
