How get an animation to play at runtime?

Hello guys!

Just wondering, i got this character i made up in fragmotion, and i exported it as an FBX file with one animation, and when i import it into unity, in the import settings, down the bottom in the preview section i can see the animation playing when i click the play button, but at runtime, it doesnt play the animation.

For an animation to play, do i need to start it manually or can i get it to play automatically?

Thanks!
