Okay, can we please get a primer that an intern can follow that starts from an empty Windows 10 install, installs everything including VSCode, flashes the boards with a Segger J-Link, blinks the LED, and single steps the debugger?

I'm serious. I will go buy any board in order to check that tutorial out.

I'll go further. I would buy the Rust folks a couple boards and Seggers to get that.
