Intro to Mission

[Sasqwatch 10]

Hi ive created a long as intro using camera.sqs but im not sure how to end the intro so that once its finished it goes straight into the mission where i am able to control a unit. Ive searched the forums and all i found was that you just have to save the mission under the same name as intro and itll work?

Can someone please tell me in detail how to do this as i am a bit of a noob who really wants to make mission on Arma 2

Thanks
