Hello, I’ve updated the Slide Show (S9) command line tool (and library/gem) that lets you write your talks / slides / presentations in plain text w/ markdown conventions. You can use any of the (Jekyll-compatible) theme packs such as reveal.js, bespoke.js, s6blank, etc. As an example, see the Blockchain! Blockchain! Blockchain! talk (source in markdown). Happy publishing & talking. Cheers.
