TS bro,
No need to complicate matters, simplicity works.
Just start off with some casual greets and topics for a start, dun want to scare her off with a too strong approach.
When she starts to take notice of you, can go on further with pasing her some nice compliments and let the flirting began!
If all goes well, next should be a date request and you should know what to do after that.
Good luck!
