 Cirno's Perfect Math Library
 ====
+
+### WARNING!!!
+Quaternion-euler conversions are currently very very broken and need to be fixed!
+
 ### Adapted for Minetest
 For best memory performance: have luaJIT & it's FFI library (this should be built into luaJIT), and add MTUL-CPML to your trusted list (so it can `require()` call the FFI library).
 
 Various useful bits of game math. 3D line intersections, ray casting, 2d/3d vectors, 4x4 matrices, quaternions, etc.
 
 This is a fork of CPML (for LÖVE/love3d), it's been ported over the minetest so it can be used in whatever you need it for.
