Where can I find step by step directions for contacting someone by FaceTime?

I have strong resistance to using FaceTime to contact people and so have never used it before.

I have no idea how this works and also could not find detailed directions anywhere.

In the same way that someone who has never used a computer or email would need to have a list of steps

that start with creating an email address,

to creating and sending messages, so do I need details on using FaceTime.

I see that it stores my contacts phone numbers and email addresses but this does not explain how you

actually use it.

I do know that whoever you contact has to be on it at the same time. This still does not tell me how to contact them. I also would like to know if Skype and FaceTime are the same thing. Can someone on Skype contact someone on FaceTime?

I opened up FaceTime and looked at it and know that I should first put on my make up. 🙂 I don't see what to do after this. I also don't see any real help section for it (which is how I learned to do Excel and WORD without anyone to help me)

Can anyone help me with this?
