I am new need help please!

i have apple tv with 2.2 software and just bought atv flash version 3.3.4.
i can’t find a instruction guide how to install it and make the flash drive.
i am new with mac system and with apple tv.
can someone please help and give me instruction?

When you download the software from your online account the installation guides/links are included in the DMG file you download.

So if you are new to mac - after you download the DMG file - then just double click on it to mount it to your desktop - then the instructions are inside.
