17.7 How many vignettes?
For simpler packages, one vignette is often sufficient. If your package is named “somepackage”, call this vignette somepackage.Rmd. This takes advantage of a pkgdown convention, where the vignette that’s named after the package gets an automatic “Getting Started” link in the top navigation bar.
More complicated packages probably need more than one vignette. It can be helpful to think of vignettes like chapters of a book – they should be self-contained, but still link together into a cohesive whole.
