Hi, I'm working on developping a website using piranha cms, however I find it weird how it feels almost impossible to find the api reference of piranhacms

I can find some documentation explaining the structure of the project etc but when it comes to describing all the classes and all their members and methods I find almost nothing.
I do need it because I work on visual studio code and the intellisense doesn't seem to be working properly in cshtml files even with the razor extension, so I wanted an easy way to be able to check the members of the classes I use

for instance i'd need the api reference of the SitemapItem class
