You can get very technical about game.
But that's not good for newbies. When you're just starting out you want to focus on the bare basics like your dress, grooming, approaching consistently, building decent state, eye contact, smiling, body posture, physical escalation, never running out of things to say, and leading.
The most important things are:
Going out at least 2x-3x nights a week, consistently
Approaching consistently
Putting yourself into a good mood while you do so
Smiling and laser eye contact
Getting good at never running out of things to say. Becoming good at holding conversation
Communicating with her man-to-woman, with clear sexual intent
Immediate physical escalation
Leading her
That will get you 90% of your results. Getting decent at all the above will take you several years of full time work.
