Adding a Project.toml to an existing package

I’ve got a repo i’ve been developing, and I would like to start laying it out properly as a package that, in principle, someong could to an add to. However, I’d prefer not to trash what I already have. Is there a way I can “just” use generate to construct the Project.toml file? I already have some of my codes in /src folder.

Probably not. Just do

] activate . 

and then ] add all the packages you currently have using in your code.

I got some helpful responses to a similar question here.
