Thanks for your edits, this is helpful!

I'd take all the edits except:

• I prefer just a plain File to describe the File variable type. No formatting please.
• We are planning to embed GitHub gists for our workflow code, so unfortunately we can't incorporate your syntax higlighting, despite as visually nice it looks.

Other files besides .Rmd were made - not sure if it was by intention. Seems to be causing merge conflicts.
