The documentation pages for pnpm link and pnpm unlink needs some elaboration, please.

Topics that could be covered/improved:

• difference between pnpm link <dir> and the other options. What is the usecase?
• The existence of both pnpm link <dir> and --dir option is potentially confusing. For example, my experiments with pnpm link --global --dir c:\some\other\folder did not have the effect I expected. (I don't really know what it did, but it didn't register c:\some\other\folder's package repo globally)
• explain more the multiple steps involved in --global linking - 1) from the dependency to register it globally, 2) from the dependent
• for unlink: "If called without arguments, all linked dependencies will be unlinked." Is this global to the machine? Is it just for dependents? Or just for dependencies? Or both, for a particular working directory?
• Are there any gotchas with mixing package managers on a system? What if the dependency uses npm while the dependent uses pnpm?
• Are there any tools for examining the current state of linked packages on the machine ("no", I think).
