When you play Minecraft you spawn with a map only and nothing else. 

When you first play minecraft you will spawn on a tree with a map in you're hands. This will help you navigate the world and find villages better.

you will come to a place later in the game called the nether.You can get lots of things that you cant get   in the over world like netherrack and glow stone and magma blocks.

When you find any kind of ore excepet iron ore you must use iron pikaxe. 

There are many different kind of swords like from wooden to diamond to enchantment.

You can enchant things like swords and axes and shovels and pickaxes .To make the entrenchment table use 2 diamonds 4 obsidian and 1 book of any kind. 

You will eventually fight a boss called the wither to summon the wither put 4 soul sand like a t shape then put 3 wither skeleton heads on top and back up when it turns white and do it away from anything that you spent a lot of time on because this boss will destroy everything in its path.  

Then the hardest boss in the game is the ender dragon you must make a portal with the things that endermen drop(which i have no idea what they drop sorry).

You can create crazy things cooler houses even a cat statue you need wool for the cat sorry.

This is a woodland mansion there are vindicators and evokers. you can get an un-dying token tho never die by fall.
