I tried to get the s5 presentation mode from https://github.com/sigma/org-s5 running, but I'm missing something. I followed all the steps in the README, but how do you generate the S5:ified html? I tried simply doing [C-c C-e b] but it did not open up in s5 mode. What am I missing? Should the generated html contain the contents of preamble in org-s5.el? It does not.

Thanks!
