How to use Markdown Extensions offline

I am not looking for the PDF generation or the formatting of Fountain, just the syntax colouring based on the Fountain scheme. I am guessing this isn’t

  2. a priority

but I’ve been reading tons of posts about Markdown (and a bunch of Devonthink stuff I didn’t know about, i.e. Imprinting/Stamps, WTF, Devonthink is DEEP!) and trying to understand how all this technology works.
