Unresolved[K-Relay] Mapcache plugin help

Canyone fill me in on how this works?

Do i have to discover the entire dungeon?
Do i have to enter a command to save a dungeon?
Do i have to wait a certain amount of time to save a dungeon layout?

Im unsure about how this plugin works but it seems amazing
