how to kiss a girl for the first time?

Ok.. so i’ve been dating my girl for about a month now.. and i’m feeling its getting near the right time to kiss her. I’ve never kissed a girl before, but she’s already kissed plenty of boys, so i want to be up to standard. However, i’ve got absolutely NO clue on how to kiss a girl. My main concern is what do i do with my lips? Do i pucker them? And where do i put them? Straight on, or my top lip under her top lip, or her top lip under my top lip, vice versa?
PLEASE HELP ME!!!!!!!!!!!!!
Thank You x
