How do I get an animation ID for a script?

I want to use an animation in a script, however, I can find nothing online on how to get the ID. (If you need specifics I'll be replying to comments.)

You need to upload it to roblox, and you do this by right-clicking the animation and then clicking upload to roblox. then you get the ID from that(it's in the link). Remember that the animation needs to be owned by you/the group that you are working on, meaning your friend's animations have to be uploaded by you if you want to use theirs.
