Documentation and manuals

Searching for detailed infromation on Design features, I noticed that the Reference manual in the Wiki (vassalengine.org/wiki/Reference_Manual) is different and less detailed than the reference manual nested in the VASSAL program.
Example: Game Piece traits

Is it complicated to update the Wiki ?

The website has two tabs on documentation: “Docs” and Wiki". They both seem to be redundant and to contain many identical links.
