Writing rules for GOT module - where to start?

Hey all,

Recently came across the GOT board game (second edition) and we love playing it in my office at work. I’m a web developer by day and have been toying with the idea of extending the GOT module for the Vassal engine by adding rules to it. Whether it be rule prompts based on user actions or enforceable rules I haven’t decided.

Not too sure where to start, should I learn the ins and outs of the Vassal engine and when it comes time should I write my own GOT module or just use the one that’s available at the moment? Are writing rules for these board games in Vassal even achievable?
