 minetest-turrent
 ================
 
-Adopted Minetest mod Simple Turret
+Adopted an abandoned Minetest mod called Simple Turret
+  
+See https://forum.minetest.net/viewtopic.php?id=3836 for details on old mod
+
+License: TBD (Original Unknown)
+
+Please note that I am not overly interested in extending this mod but I may entertain minor tweaks or changing an image or two, if provided.
+
+Tested: Minetest release 0.4.7 on Windows.
+
+Dependencies: Just Default.
+
+I may flesh out this file later on. I'm learning Lua so expect to see some formatting changes due to better formatting due to Style Guides.
