"Getting Started", "Although you have plenty of missions to accomplish, remember that you are still in a sandbox; the world is yours to mold and do with as you please. 
On your first day, break blocks, build a shelter, and gather whatever resources you can. 
Many players will be tempted to try to accomplish their goals as quickly as possible. 
That is wrong. Take your time and don't be upset if you can't find coal or make a bed on your first day. 
As long as you are safe from mobs by nightfall, that's a good enough start. 
With this said, go out and start your adventure!"
