+[mod] 3d wielded items [wield3d]
+================================
+
+Mod Version: 0.5.0
+
+Minetest Version: 5.0.0 or later
+
+Decription: Visible 3d wielded items for Minetest
+
+Makes hand wielded items visible to other players.
+
+By default the wielded object is updated at one second intervals,
+you can override this by adding `wield3d_update_time = 1` (seconds)
+to your minetest.conf
+
+Servers can also control how often to verify the wield item of each
+individual player by setting `wield3d_verify_time = 10` (seconds)
+
+The default wielditem scale can now be specified by including `wield3d_scale = 0.25`
