Hello, welcome back to the Ruby Advent Calendar 2017. Let’s continue the series on Day 18 with slideshow (s9) - Write your slides / talks / presentations in (structured) text with formatting conventions in markdown - kramdown really ;-); build (static) webpages w/ (jekyll-compatible) theme packs incl. Reveal.js, Bespoke.js, Impress.js, and many more. Happy writing, publishing & talking. Cheers. PS: You’re more than welcome to send in your articles (about your library / gem of choice) too!
