Should I start a Roth IRA and give some details on what it is?

I am 15 and have learned that the social security will run out when I am eligible. I read this article if you put a starting amount, of $100 in it, and then $10 every month, I would probably put more in it. you will have a cool starting amount of $1,000,000 by the age of 65. From what I have seen it is kind of like a savings acount. I do have a job, so I would be able to put money in it.
