Getting started was a breeze. Just insert the batteries, insert the USB plug, and away you go.
HOWEVER, I do NOT recommend this keyboard or mouse to anyone.
------> Edited after more use: The mouse is okay, but not great as I'd originally stated. It works exactly as stated if I'm within 3 FEET of the wireless receiver, but even just 4 FEET away the mouse is spotty and does NOT work properly. This is particularly upsetting when they claim it has "10m(33 feet) without any delays." It fits my small hands well and is super quiet. I would not recommend it for men or people with larger hands.
------> Edited after more use: I stopped using this after just 2 days. The ALT key has serious issues and only works if you hit it several times, and sometimes you have to actually jab at it hard. The keyboard is smaller than I expected because the ad says it is full size. It is also not nearly as quiet as I expected. I doubt I will keep this keyboard, but if I do, buying something to raise it up and rest my wrists on is a must.
I'd also recommend getting something with a light. There is a super tiny indicator light that comes on when you touch the keys, but it doesn't give off any light and goes off quickly when you stop touching them.
I saw in the questions that someone asked if there is an indicator light for number lock. The seller responded yes, but that is misleading. That tiny little light does come on when you touch the key, but it doesn't stay on to indicate that you still have number lock on.
