Documentation for the above template (sometimes hidden from view).

This template states whether the game observes the XDG base directory specification.

  • 1
Possible values: true, false, other
Use true if the games observes all parts of the specification, including where to save if the value is not set (~/.local/share/, ~/.config/), as well as using either the environmental values XDG_DATA_HOME, XDG_CONFIG_HOME or both. Sets Property:Linux XDG support to true.
Use false if none of the above are followed. Sets Property:Linux XDG support to false.
If the case is different (environmental values are observed but not the default location, game crashes when value is set), enter a custom text describing the issue instead, like so {{XDG|Custom text goes here.}}. Sets Property:Linux XDG support to other.
