The XHTML offline version contains almost everything the wiki has to the exception of dokuwiki info/syntax pages, template pages and some wiki guideline pages.
The best way to navigate these version is by the table_of_content.html, it's an index that was made specifically for this version since exporting the pages Body only remove the side menu (which was no longer on the side anyway but at the bottom of each page so I removed it).
One thing that needs a fix: The image galleries do not show the arrows and quit button (which still work if you know where they usually are), you can however navigate a gallery with the left/right arrows and press quit with ESC.
If you create a new wiki page and want to add it to the offline version, add the link at a logical spot in both the toc and table of content files. Here are the links:
