As the title says How do you successfully install a downloaded playermade tardis so you can use it on your worlds?

Where did you even download one?

From another friend here.

... Is it a schematic orrr?

A what?? It was done on the server I think or on a single player world. Because it says in the chat that screen shots were taken.

I think... I can't really remember as I downloaded it on the 27th of the 4th this year.
