"Creating Zoo plugins" vs "Creating Plugins that use the Zoo"

What’s the difference between this and this page on the developers website?
From the title I would think they’re the same but it seems like the instructions on each page differ. So which guide should you use for which purpose?

Hi @siemen,

If you want your Rhino plug-in to support the LAN Zoo, then you need do both.

1.) Write a plug-in for the Zoo that knows how to validate your license key. In doing this, users will be able to add your licenses.


2.) Modify your Rhino plug-in to ask the LAN Zoo for one of your keys.

Does this help?
