Create ePuB of user guide
The PDF is a great format for printing out, but for reading on an e-reader, on a mobile phone etc., a more fluid and flexible format is best.
The standard format for such is ePub – which is basically zipped (X)HTML and CSS.
It would be great if the user manual was available in ePub as well.
There are many ways to covert from MarkDown to ePub, if #20 gets done.
But even if not, there are ways to convert .lyx and LaTeX to ePub as well: https://wiki.lyx.org/GSoC/XHTMLePub
