+For a description of this Minetest mod, please refer to the forum topic:
-
+https://forum.minetest.net/viewtopic.php?f=9&t=10265
-This is a modified version of lkjoel's nether mod.  
-Look here if you want to see the differences:  
-https://github.com/HybridDog/minetest-nether/compare/lkjoel:master...master  
-Sadly lkjoel's one disappeared…
-
-Thanks a lot to LeMagnesium, crabman77, Ombridride, Gael-de-Sailly, ObaniGemini and other people from server-minetestforfun for working on this mod.

 TODO:
-— find a way to get the perlin noise inside [-1; 1] or use another noise  
+* Find a way to get the perlin noise inside [-1; 1] or use another noise
-— add something containing items to that buildings  
+* Add some node which containing items to the simple pyramid "buildings"
-— update leaves visual_scale
+* Change the sky background, fog, etc. in the nether
+* Improve the guide formspec.
+  Writing it in Markdown would be nice.
