Use this template (like this: {{Station-OXP}}) on pages about OXPs that add new types of station to automatically put them in the correct categories.

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

Station OXPs are listed at Category:Dockables OXPs.
