Use this template (like this: {{Dockables-OXP}}) on pages about OXPs that add carriers, stations, or other dockable objects to automatically put them in the correct categories.

Do not use this template on pages about each individual dockable in an OXP, only on a page about the OXP itself. (For OXPs with only one dockable in, it’s appropriate for a single page to describe both the dockable and the OXP as a whole.)

Dockables OXPs are listed at Category:Dockables OXPs.
