'Add a custom pfsense tab into its UI

I have a project in which I need to interact with Pfsense's UI, by adding an additional functionality, but I can't find anything in this regard. More specifically, I don't know what files to add, what files to change that most importantly how do I see my changes in real time. After all that I need to make the "changed" file into a installation file, where in this case I have a problem too.
