+## Create Slideshow
+
+The notebook `slideshow.ipynb` is formatted specially to be presentable
+as a series of slide shows. This use the jupyter `nbconvert` tool to
+generate a `reveal.js` presentation. These presentations, once started,
+have one or more slides that can be traversed using the right (next) and
+left (previous) arrow keys. Slides may also include "subslides" which
+can be accessed using the up/down arrow keys. Use `Esc` to see an overview
+of the entire presentation.
+
+To convert the notebook to a slideshow presentation and serve it immediately:
+
+```bash
+jupyter nbconvert slideshow.ipynb --to slides --post serve
+```
