+Axes
+----
+The coordinate system is the same as that used by MineTest; Y is upwards, X is perpendicular, and Z is parallel.
+
+When an axis is specified in a WorldEdit command, it is specified as one of the following values: x, y, z, or ?.
+
+The value ? represents the axis the player is currently facing. If the player is facing more than one axis, the axis the player face direction is closest to will be used.

 Regions
 -------
 Most WorldEdit commands operate on regions. Regions are a set of two positions that define a 3D cube. They are local to each player and chat commands affect only the region for the player giving the commands.
