This may qualify as a dumb question, but I am not clear based on everything I have read and viewed thus far. Will this generate the final site files that will end up on my hosting server? Thanks!
Adobe XD will not generate any code, you or a developer will have to write the code to create your app or site or whatever you are designing!
However you can use the File > Export (Cmd+E) functionality to export assets from your design to images, which can then be used when developing.
