How to create Provisioning File

I new to iOS development, and I want to run my app on my iPhone. I have connected it to my laptop but no prompts show up. I read all these tutorials on how to add a device and stuff but it really is confusing for me, because none of it is happening for me.

I am probably going to be down voted cause this is a stupid question, but my brain is rattled: How do I create a provisional file, and use a device for development? Please make it really detailed, cause Apple's description are kind of vague.

(The thing is when I press the plus button in iOS Provisional Profile in Member Center, it can't detect a device that has been connected. If that way is wrong, you know why I am confuse.)
