Lets explain the layout of the project.
This is the basic layout of repo:
docs/ media/ src/ - DevScripts/ - DevTools/ - Docs/ - Imports/ - Packages/ - UnityWebBrowser/ - *Other UPM packages*/ - ThirdParty/ - UnityWebBrowser.Pages - UnityWebBrowser.Engine.*/ - UnityWebBrowser.UnityProject/ - VoltstroStudios.*/ - *Misc Stuff*
src/ are all fairly explanatory.
DevTools/ provide developer scripts and other external applications that are needed.
Docs/ provide a way of building the UWB package as a dll, so docfx can use it.
Imports/ contains shared
Packages/ contains the UPM packages.
ThirdParty/ contains stuff that ain't ours.
The rest of the folders contain dotnet projects, with their respected code.
