Equipment for recording video

I am about to start recording video for my course that I will put on teachable. Tonight I watched your new make a million dollars video (amazing!). I had the enlightening thought that I could record myself just like you did in that video. 🙂

Can you share what specific equipment you used to record that video?
It looks like you are sitting at your computer?
Mic? What does it plug into?
Camera? or on computer?

Thanks soooo much!
