How do i add a 2d animation to Unity 2D ?

Hi just wanna know how to import and see a gif in Unity 2D, like water, just for decoration, no interractions. And infinite loop.

Hi,
Unity is not designed to support GIF files. Instead, you may choose to use sprite animation. You may also want to get it converted to an MP4 video file. You may consider using Unity version 4 as well. Visit the Main Menu and then select the Game Object. For detailed instructions, you may consider visiting https://answers.unity.com/questions/674367/how-to-use-this-gif-in-animation.html.

Thank you ! Yea i just need it to be an animation for the background, ok i will do that.
