 Submit a pull request to install `workflow` for repository `repo`. This version of `install` is
 designed to work in concert with [GitHub.jl](https://github.com/JuliaWeb/GitHub.jl), so that you can run queries, filter results,
 and then submit changes. See the documentation of that package for more detail about `repo` and `auth`.
 
+`pkg_url_type` can be `:html` or `:ssh`.
+
 The remaining keywords are all strings, and have generic defaults but allow customization.
