How would I script an automatically sliding door?

I am trying to build a door that automatically slides open and closed. It's going to look like a sliding door you'd see at a supermarket.(two doors that slide away from each other. If you need more detail, look at this and imagine that a bracket= a door. Closed: [] Open: [ <- -> ]) When I tried to do it I ended up clueless. Any help?

What I would do is out and invisible brick in both sides of the sliding door and when someone touches the brick it would do a for loop

For i = 0, 100, 1 do game.Workspace.slidingdoor1.Position.X = i End

Do the same for the other panel but in another function other wise one door will open and the other will wait for that one to open

I would do exactly what Kurokku said,
