A sample is really not needed, as it's the mechanical process of drag and drop that is at work here. A sample would just show an animated sprite, which is effectively useless.
Just start a new project, then drag any .gif from your PC and drop it onto the Layout anywhere. The .gif will be turned into an animated sprite.
If you're not comfortable with the Drag and Drop process, then the long way is to Press right mouse and select 'Insert new object'.
Choose sprite and click anywhere on the Layout. The Image Editor will automatically launch, allowing you to create or load your graphic for the sprite. In the 'Animation Frames' window, press right mouse and select 'Import Frames' and navigate to where you have your .gif file. The gif will be loaded and split into it's original frames.
