I am trying to get documentation to show up for an actual package (not its functions, since that's done automatically when documentating the package) through the help() or ? functions.
For example, using the following:
?dplyr
We get:
dplyr-package {dplyr} R Documentation
dplyr: A Grammar of Data Manipulation
Description
To learn more about dplyr, start with the vignettes: browseVignettes(package = "dplyr")

[Package dplyr version 1.0.7 Index]
I created a basic package, cats, through Hillary Parker's tutorial: https://hilaryparker.com/2014/04/29/writing-an-r-package-from-scratch/. I installed it and confirmed that it works correctly, e.g., getting help docs for the one function:
?cat_function
Gives:
cat_function {cats} R Documentation
A Cat Function
Description
This function allows you to express your love of cats.
Usage
cat_function(love = TRUE)
Arguments
love
Do you love cats? Defaults to TRUE.
Examples
cat_function()
[Package cats version 0.0.0.9000 Index]
However, trying to get docs for the package itself:
?cats
No documentation for ‘cats’ in specified packages and libraries:
you could try ‘??cats’
From the function help, I can click on Index, and then I get an OK "help" page, and I can also from there click on DESCRIPTION file, but these are definitely not like what help(cats) would output.
How can I get the same help() call for my cats package? I think I must have read all tutorials about creating a package but only saw something about adding vignettes which seem to be a different thing (though I did try adding a vignette, and the help docs still didn't come up). I also tried adding a readme file, but alas, same result. What's the trick? =)
Edit: Actually been using usethis through devtools to install and document() but I don't think this would make a difference as I didn't see this particular form of package documentation documented on any of the tutorials.
