How do I make friends?

I’m up for some wit, per me placing this in Social, but I’m really looking for help.

First time seeing me? Here are my previous two questions.

It seems like I finally need to interact with people. I am that characteristic introvert at a high school, with literally no friends. I am just clueless when it comes to meeting people for the first time, at high school in particular since there really isn’t another place to go. Or, maybe, that’s just how clueless I am.

I really don’t know how to begin talking about it, even. Wow. Help. ◉︵◉
