How do I add a signature?

[Paradox Cubing]

Hi guys, I'm having some trouble adding a signature on my profile. I've seen everyone with them, it's the little text at the bottom of everyone's posts. I think you ave to go to the about me part and it should say 'signature' and then I can edit it. But it doesn't say signature anywhere, Ive seen it on other peoples' profiles. Help please?
