I got H2N4 Pro, now what?

Right so I was advised to get H2N4 to plug my leaks and better understand how my player pool can be exploited. I don't know how to proceed. What metrics would I do well to look at, build popups, huds, compile reports for, etc? What spots am I to pay attention to? When I find a leak, what does plugging said leak look like/entail?

I'm open to learning how to build my own reports, or buying and affordable package to analyze my play if there is such a bargain. I appreciate the articles on the site but they are more functionality of the software without a lot of poker strategy in mind.

If this has been addressed already and it's easier to refer me I'd appreciate that. My knowledge beyond basic poker stats is fragmented if not limited. Not specific to H2N4. Thank you.
