+# Lumberjack
+
+A simple mod based on ideas from the mods TreeCapitator, Timber, and New Timber.
+This mod allows to hit the bottom of the tree and the whole tree (wood) is harvested
+and moved to the players inventory.
+To distinguish between "grown" trees and playes tree nodes, the 'node.param1'
+is used to identify placed nodes.
