Hello.

I know how to add a development version of a registered package

```julia
add PackageName#dev

```

Also, I know how to add an unregistered package

```julia
Pkg.add(url="<git path>/PackageName.jl")

```

However, I have tried lots of ways of trying to combine these to add a development version of an unregistered package, but noting I have tried has worked.

Is what I would like to do even possible?  
Thanks for any help

Not sure why you use the Pkg REPL-mode when only specifying the git revision, but not for the url/unregistered package.

* * *

In the Pkg REPL-mode, you add the package with:

```julia
(@v1.5) pkg> add <git path>/PackageName.jl#dev

```

With `Pkg.add`, you provide the `rev` keyword argument as well to specify the git revision:

```julia
Pkg.add(url="<git path>/PackageName.jl", rev="dev")

```

Thanks so much! I looked for quite a while and could not find any explanation of that combination.
