Hi and welcome to Fluther! It’s a fun and addictive engrossing site.
This question has been asked many, many times in the past week, so we’re a little fatigued on the subject. You’ll find lots of answers if you search the site for previous versions of the question.
My standard answer is flirt first, build up to a coffee date (or any casual, short date), and build that up to the big finale. For more detail, read How to Succeed with Women by Louis & Copeland. It’ll make dating a breeze.
