Tutorials/Skyblock

Skyblock is a popular challenge, where the player starts the game in a small island in the void, including a tree and often a chest, which contains items you couldn't get without it (for example lava buckets).

Many different variations of the skyblock map are available online.Iron ingots is rare drops to the zombie.

Overworld only

With access to the End and the Nether
The making of the Nether portal is similar to that in normal minecraft

Tree farming
Wood is crucial in the beginning of a skyblock map because it is the only renewable block available in the beginning of the game (except if you have immediately access to lava and water, in this case you can make a cobblestone generator).

First, chop down your island's tree, and make sure to get all of the dropped saplings. Then, dig all the dirt of island, except the first layer. You will then use (almost) all of the dirt to create a tree farm and use the wood you collect to make wooden slabs and expand your terrain using them.

Popular maps
Skyblock has many variants.
