 Position and size units are inventory slots, `X` and `Y` position the formspec
 element relative to the top left of the menu or container. `W` and `H` are its
 width and height values.
+Inventories with a `player:<name>` inventory location are only sent to the
+player named `<name>`.

 When displaying text which can contain formspec code, e.g. text set by a player,

 For coloured text you can use `minetest.colorize`.
