accidently removed device from icloud
So I recently got my iphone stolen from me and i was going to use Find My IPhone on www.icloud.com to find the location of it. This was the first time something like this happened to me so i didnt really know what to do. i accidentally clicked on the button that removes my iphone from my icloud. I felt panicked at the moment so i wasnt able to read what i was clicking on. The next thing i know, i had delete my iphone from icloud. Now what i want to know is HOW i can get it back to my icloud so I can maybe find it. Thanks
iPhone 5s
