Hello I'm writing this guide for beginners of Minecraft.

 So it's your first day and night, the first thing you want to do is collect wood. When you have a good amount you want to craft a: crafting table, pickaxe, axe, sword, hoe and shovel. When you have some tools you want to mine a house (close up cave if there is one). After you've made your house craft a: chest and furnace. 

 So you have survived your first night, well done. But now you want to think about food. I recommend making a wheat farm for the beginning. But after you have some bread use your sword to kill some:Chicken, pig and cow. Afterwards you want to kill sheep for wool to craft a bed.
