Tested for Minecraft version 1.8.8, should also be compatible with 1.8.9.

Put the "End-Bringer Pack" in your resourcepacks folder

(which is in: AppData\Roaming\.minecraft  if you're on a Windows 7 PC)

Then, put the "End-Bringer (Fixed)" folder in your Saves folder.

Set your language to Enderspeak (ED) for the full experience.

Be sure to explore the "End" before you set off to the Earth warp pads; there are valuable NPCs to meet, and the Queen herself has instructions.

Remember, you have Enderpearls (Blink) for a reason, use them when in doubt.

Have fun, do lots of exploring!
