+## Pandoc and reveal.js
+
+[reveal.js] is a javascript framework to produce clean and dynamic slides. My
+settings to generate them are liberally inspired by [Pablo
+Coves](https://pcoves.gitlab.io/blog/pandoc-markdown-revealjs/).
+
+[Pandoc] on the other hand is a document converter tool that supports a very
+extensive spectrum of formats and syntax. My most use case is to convert
+markdown to some other reflowable format (usually html, and sometimes epub).
+
+Using both in conjunction allows for quick and dynamic presentations which don’t
+require _accuracy_ in placements. That may be the case for lightning talks for
+instance. The main advantage compared to the two above solutions is that
+[reveal.js] takes advantage of web browser capabilities to produce dynamic
+transitions. Those are otherwise hard to get from PDFs (some people made custom
+pdf reader for that).
