Map Info:
Basically, you start on a big floating square in the sky. You can find caves in every square. The first square has iron and coal, and the rest of the squares get better for each one you get to. The next one has gold, then the next is redstone, then lapis lazuli, then diamond. The last one doesn't have any ores, just dungeons. The dungeons currently don't have amazing stuff in them.
Look around the map if you feel like it though. When I get bored making this, I put random stuff in it that might help you. I recommend multiplayer in this map, as it does get fairly difficult, and you would get through it faster.
Creating a Nether portal is actually against the rules, because the Nether is in the normal world. You can find nether islands to the west of every other island. For example, the second island has a nether island to the west of it, then the 4th island has one, and the 6th island has one.

The first nether island has zombie pigman spawners, with some soul sand and fire. The second one has glowstone and ghast spawners, and everything from the island before it. The third one has a nether fortress, and all the stuff from the one before it.

Since blazes can't spawn in the normal world, I put chests with blaze rods in them in the nether fortress.
The End is currently pretty big. There's a huge square as big as the normal ones in it, but it's made of End Stone. It also has obsidian pillars on it with chests in it. Just make sure you kill the enderdragon when it's above some blocks, or you'll miss all the experience orbs.

I have plans to make there be 3 enderdragons to make it harder. There aren't any Ender Crystals, cause I couldn't figure out how to spawn them.
