there's a section marked "Installation Tutorial". Someone wanting to install packages should be able to get into that, once it actually has content : )
IMO, we should put the energy into one comprehensive document (the new user guide) and link out to it, not duplicate effort into the core docs.
The "Installing Python Modules"/"Distributing Python Modules" documents should be integrated into the new User Guide.
It will be confusing and anti-zen for a user to come upon those documents and have to reconcile it with the user guide
