Install a second NuGet from the first

I've created my own NuGet package, but I would also like the user to install another NuGet package alongside the one I install. Is there a way to automate this process in an install.ps1 script, or some way like that? For example, let's say when someone installs my nuget, I also want them to install "Newtonsoft.Json." Or is there a way to add another package as a dependency for the first one?
