How do I add my phone to "FIND MY'?

Re: "How do I add my phone to "FIND MY'?" : "I haven't been able to find my phone with the "Find Me" text.

So how do I add it in?"

I cannot find "find my" anywhere. So whenever I misplace my phone, I have no way of locating it. It is not what someone wrote earlier, to go to 'sytems', click on my name and then click on 'find my'. It is just not there.

Try Settings > [Your name] > Find My
