Getting started with Muse 2

Hello, my Muse 2 just arrived!

I am a developer, so I was wondering what are my choices with Muse and Windows so I started searching more deeply now that I have my device.
I have heard about an SDK but then I got into the website and understood that it is discontinued. Am I right?
I also heard about Muse Direct (in order to get raw eeg data), but I cannot download it. Windows 10 store link says that “Muse Direct is currently not available.”

Could someone help me out?
Thank you in advance,
Amalia
