How to login to facebook?

1) Sign up for a facebook by going to facebook.com, filling out the Sign Up information, and then verifying your identity.

2) Later, return to facebook.com and type in your email address and password.

3) You are now logged into facebook, congratulations.

(I put the first bit about signing up for one in there because I couldn't imagine someone having an account and not knowing how to sign in seeing as it's so blatantly obvious there at the top of the page. I don't even have a facebook and I know how to do it.)
