Question about parsing replay files

Hi, I'm a computer science student at the University of Adelaide and I am working on a project which focuses on combining the game commentary transcript and replay statistics using GPT to improve the professional player’s efficiency.
I downloaded some replays and parsed them using S2Protocol(https://github.com/Blizzard/s2protocol) and found a lot of information but don't know what to use. I parsed game events but couldn't understand the meaning.

I would really appreciate it if you could let us know how to parse a replay file. For example, where could we find the data for units or buildings, like location, action, clusters, birthtime, dead time, attack/track, abilities, building type, building orders, etc.. Besides, there is still some raw data we can’t figure out the exact meaning of some attributes. We are very interested in knowing where we can find the complete documentation.
Thank you and this repo is so helpful to us who would like to try to analyze data from the SC2 game.

No repository file or test is named. Start with the linked Blizzard S2Protocol repository and the parsed-event example in the issue, then determine whether sc2reader exposes the requested unit and building data. Done would require a concrete documentation path for those fields and clarification of the unexplained raw attributes.
