We have enhanced our SynProject Open Source tool, so that it is now able to generate its documentation as HTML, in addition to doc/pdf documents.

You can take a look at this web page.
It contains the whole SAD 1.18 content.
The pdf is more than 16 MB, whereas this html page is only 6MB.

Note that all diagrams were embedded as SVG within the page content: resulting file will be much faster to browse and download.
But it would require a modern Browser. For instance, older Internet Explorer revisions do not support SVG, but latest IE 11 does (as Chrome, FireFox, Opera or Safari).
We tried to implement some basic responsive design layout, for tablets or phones.

I hope this would help accessing the right information.
Do not forget there is the Table of Contents, and an index of KeyWords!
