How to Get a Gif as Your Signature?

[Krumblez]

Alright, so I'm a total nub and I have no idea how to have a gif as my signature. I see a lot of people with really funny gifs in their signature and I want to be funny too! Can anyone please explain to me step-by-step on how to get a gif as my signature. Sorry, but I'm not good with anything computer related xD

For me, I just have to copy the gif and paste it into my signature.
