+# Test Nodes
+
+This mod contains a bunch of basic nodes to test development stuff.
+Most nodes are kept as minimal as possible in order to show off one particular feature of the engine, to make testing stuff easier.
+
+This mod includes tests for:
+
+* drawtypes
+* paramtype2's
+* node properties such as damage, drowning, falling, etc.
+* other random stuff

+--[[ Drawtype Test: This file tests out and provides examples for
+all drawtypes in Minetest. It is attempted to keep the node
+definitions as simple and minimal as possible to keep
+side-effects to a minimum.
+
+How to read the node definitions:
+There are two parts which are separated by 2 newlines:
+The first part contains the things that are more or less essential
+for defining the drawtype (except description, which is
+at the top for readability).
+The second part (after the 2 newlines) contains stuff that are
+unrelated to the drawtype, stuff that is mostly there to make
+testing this node easier and more convenient.
