 <h3>Noise parameters</h3>
+<p><b>NOTE</b>: This feature is still experimental and has a few minor bugs regarding display and selection.</p>

 <p>This is fairly advanced and most games don’t use this. You can use this if you want to see what happens if you use non-default heat and/or humidity Perlin noise parameters. This corresponds to the Minetest settings <code>mg_biome_np_heat</code> and <code>mg_biome_np_humidity</code>. The explanation of Perlin noises is out of scope for this document. See the Minetest Lua API documentation.</p>
 
 <p>Changing the noise parameters has an effect on the possible value range for heat and humidity which is why this has been included. This also means the recommendation that you try to keep biomes between a heat/humidity roughly between 0 and 100 goes out of the window; you have to figure out a good range yourselves.</p>
