+# 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.

+
+The following nodes can be used to demonstrate the TGA format support.
+
+Minetest supports TGA types 1, 2, 3 & 10. While adding the support for
+TGA type 9 (RLE-compressed, color-mapped) is easy, it is not advisable
+to do so, as it is not backwards compatible with any Minetest pre-5.5;
+content creators should therefore either use TGA type 1 or 10, or PNG.
+
+TODO: Types 1, 2 & 10 should have two test nodes each (i.e. bottom-top
+and top-bottom) for 16bpp (A1R5G5B5), 24bpp (B8G8R8), 32bpp (B8G8R8A8)
+colors.
+
+Note: Minetest requires the optional TGA footer for a texture to load.
+If a TGA image does not load in Minetest, append eight (8) null bytes,
+then the string “TRUEVISION-XFILE.”, then another null byte.
