How-to download all openwrt wiki/documentation?

Is there a way to download openwrt wiki/documentation for offline use?
Some projects offer theirs on github.com as markdown files, so I was wondering!

wget -m -np https://openwrt.org/docs/

will return a Error 429: "Too Many Requests", and limiting with --wait is very slow.

Thanks!

After doing tryouts with different dokuwiki export plugins I'm sorry to say: There is currently no working way to export the wiki to html or PDF.
