Resources include trees, ores, long grass, pumpkins, giant mushrooms, underground gravel (and dirt) and a few other things all in a single package

That's the thing you give to Minecraft so that it can generate your lovely mega flat world for you. When creating the world, choose Superflat, click Customize, Presets, click into the black text box at the top, do CNTRL+A and delete (backspace) OR rub it all out. Then copy the generator code and click into that black text box and do CNTRL+V or copy it out.

Advanced Mode - Allows you to enter custom blocks ids to use any blocks, even from mods or modpacks! :D
