Taking Inventory (Achievement)

Taking Inventory is the first and easiest achievement added in the Minecraft Beta 1.5 Update.

[edit] What to Do

You must open up your inventory.

[edit] How to Complete

Firstly, check your Minecraft settings to find out what key you have set to open your inventory. (By default it is either the 'E' key or the 'I' key.) Then enter the game, and press that key to complete the achievement!
