Funny, I just implemented wkhtmltopdf yesterday (via ruby's PDFKit) for invoice generation. None of the issues listed are a big deal for our very simple use case, but I did have to rebuild docker images a bunch of times in order to figure out the right dependencies on debian. I couldn't find a canonical list of these anywhere. The binaries installed through apt-get are also outdated and didn't work for me, so I ended up using the wkhtmltopdf-binary gem.

These are the os dependencies I ended up needing: libxrender1, libxext6, and libfontconfig.

So yeah - the library is fine, but installation ux/docs could use work.
