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

```julia
] activate . 

```

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

I got some helpful responses to a similar question [here](https://discourse.julialang.org/t/what-are-the-steps-to-create-your-own-package-in-julia/40877/15).
