Step one: Say "Hi, my name is _____, nice to meet you."

Then follow the usual rules when meeting a person for the first time. You know, ask them where they're from, what they do for a living, and such and such. Talk to them, make conversation, learn about who they are while telling them about yourself. It's not any different at all from trying to get a date with a vanilla person. After you've talked for awhile, if you feel like things are going well, ask if they'd like to meet you again. And then go from there.
