 Welcome to MathWorlds!
 
+So far, MathWorlds allows you to create a world defined by an implicit relation f(x,y,z,c)=0.
+
 Just compile the game as you would with minetest and then choose 'MathWorlds' in the mapgen menu! Have fun!
 
 Don't forget to add ''static_spawnpoint = 50,20,0'' to your minetest.conf file or else you will fall into INFINITY!!
