How to make portals?

It appears that the de facto standard for portal creation on Sponge is Project Portals.

Unfortunately it appears that the documentation and examples are non-existent or at least abysmal. There’s no real explanation of the portal creation process. Previous portal plugins we used years ago were pretty simple where you’d just aim make a portal with a name and then go to another and name it and connect the two.

This portal process creation with Project Portals seems entirely foreign… Can someone please provide some example usages with all accompanying commands that are needed to create a portal system?

There is a basic portal creation guide in the wiki :

I made it with real used commands. Also you can look for “creation” inside original topic.
