 <h3>Export</h3>
 <p>This allows you to export the current biomes into a text. You can choose to export them either to Lua code or JSON. The export only includes the basic biome info but not stuff like biome color (which is only relevant for MiBPoV) or noise parameters.</p>
 
-<p>The Lua export gives you a very basic Lua code that can be pasted into an actual Lua mod. The code is very basic and does not include the “landscape materials”, like what the surface is made of (dirt, stone, sand, etc.).</p>

 <p>The “Clear” button clears the previous export. This is just there to reduce clutter on the webpage.</p>
