Help setup development

Hi,
I am a long term Musescore user, and software developer. I would like to explore the code and contribute. I have experience with Android Studio and XCode, but not Qt (I have basic knowledge of C++). I have everything installed but I am blocked with the initial Qt setup for the project. The instructions online seem outdated regarding the latest QtCreator version. If someone has time I could benefit from a quick chat to sort it out. After that, I am confident I can learn and maybe start contributing easy tasks. Thanks
