When you do `Pkg.add` of a local path, it will pick up what’s committed to git and ignore local changes. When you do development of a package you should almost always either use `Pkg.develop` or activate the environment of the package itself.

What is in that `Project.toml` file? Does it have a `name` entry?

In my fork was no file `Project.toml` included.  
What is the clean way to add to my fork a proper `Project.toml`?

This question from you was a trigger 🙂  
I have copied the `Project.toml` from the original package and replaced the `uuid`.  
The new uuid was generated via the command:

```julia
import UUIDs; UUIDs.uuid4()

```

Now I was able to send the command:

```julia
Pkg.develop(path=raw"C:\folder\to\my\local\fork\EquivalentCircuits.jl")

```

Regarding this, I have a question:  
I guess this command links / adds this fork (forked package)  
to the current environment and this command is a replacement / alternative to the Pkg-command:  
`Pkg.add()` Is this correct?
