Is the main documentation available as a PDF document? I see the faq, and the Getting Started documents as PDFs, but can’t seem to find the main documentation in the same format.
I don’t think the other pages are having PDFs generated. You can use your browser or OS’s “print to file” feature on the pages you want.
If that doesn’t look good enough, you could download the documentation from GitHub, edit the parameter
latex_documents in the file conf.py so that it includes all the pages you want, then run
make latexpdf (or
make.bat latexpdf on Windows). This will require installing Sphinx and TeX Live.
