Noticed that the example files for making nodes now have changed since I got started with it. Without the reliance on .pro files for QT-creator, it is now even easier to get started - and you don't have to deal with the whole QT-creator licensing thing.
Install CMake, Download Visual studio code (MS but open... or something like that), install CMake for VSCode and CMakeTools inside VSCode*, open the example folder and you should be set! :)
*you might have to enter the path to CMake in the VSCode config
