This should fix it...

usethis::use_vignette("tmp")
unlink("vignettes/tmp.Rmd")

I'm not exactly sure how to get #77 working, the example in there reports 0/2 tests passing... But I want to at least get some writeup online as soon as possible.

#77 isn't a critical priority right now since it's only for the standalone case, not within learnr. But, it is something that should eventually work

#81 got merged!!!

I'll fix up the vignettes in here (this will also update the pkgdown website)

Closing this PR in lieu of #102
