+Fireflies
+===
+
+Adds fireflies which can be caught in a net and placed in bottles for lighting
+
+Intro
+----
+
+This is a simple Minetest mod by Shara RedCat that adds fireflies to the world on mapgen, which can then be caught in a net and placed in bottles to provide light. Note that they only appear on newly generated map.
+
+This mod was originally adapted from the Hidden Worlds subgame to work with Minetest Game, and has since been added to Minetest Game itself. This version (at https://github.com/Ezhh/fireflies) is now maintained independently from the main Minetest Game version for the purpose of possible expansions to the mod which may or may not also be added to Minetest Game at a later time.
+
+Thanks to shivajiva for helping work through the original idea and for assisting with the code, and to all those who helped test this mod so far.
+

+
+Compatibility
+----
+
+Please note that the current stable version of Minetest (0.4.16) is unable to position the fireflies above groundlevel. The mod is otherwise fully functional and can be used; but requires the current dev version of Minetest for optimal firefly placement. 
+
+License
+----
+
+Code for this mod is released under MIT (https://opensource.org/licenses/MIT).
