what’s a good workflow for developing existing julia packages?  
specifically, I’m looking for a good detailed workflow for making changes to an existing package, loading the modified version, and testing the changes with other scripts, as smoothly as possible.  
Thanks

The first steps I usually do are:

```plaintext
pkg.activate --temp"
pkg"dev PackageToModify"

```

Then fork the package om github, and add that as an additional remote for the package.

If that is a package you developed you can follow the steps mentioned in [this link](https://julialang.org/contribute/developing_package/#:~:text=How%20to%20develop%20a%20Julia%20package%201%20Step,...%205%20Step%205%3A%20Register%20your%20package%20).
