For a description of this Minetest mod, please refer to the forum topic:
https://forum.minetest.net/viewtopic.php?f=9&t=10265
TODO:
* Find a way to get the perlin noise inside [-1; 1] or use another noise
* Add some node which containing items to the simple pyramid "buildings"
* Change the sky background, fog, etc. in the nether
* Improve the guide formspec.
Writing it in Markdown would be nice.
These could be useful:
