Hi all,

I have a question about the behaviour of Base.find\_package.  
I know package can be found :

1. if the package is already installed.
2. by `using CSV`

But when I follow this tuto: [How to develop a Julia package](https://julialang.org/contribute/developing_package/) for developing package, I get output from `Base.find_package("YourPackageName")` (without `Pkg.add(pkg)` nor `using pkg`).

I can’t get any clue from here ([julia/base/loading.jl at master · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/blob/master/base/loading.jl#L2177))  
Does anyone know what happened?

```julia
julia> using PkgTemplates
julia> t = Template(;

               Git(),
               GitHubActions(),
           ],
       )

```

Considering this is in the “New to Julia” category, why do want to use `Base.find_package` at all? Please note that it is an internal function not part of the public interface (because it has no docstring). So what is it you want to achieve? Perhaps there is a better way of doing that 🙂
