@U1Z392WMQ where to find a .session file?

that’s your logged-in cookie from advent of code. you can see it in chrome dev tools.

ah, ok, thanks

@U1Z392WMQ very cool! How did you learn to do this? How do you make it work within github site?

learned it by puttering around for a decade. The script creates the image, which I then put into the README markup like any other. I have to run this manually every time I solve a new one. Sometime this year I’ll make it a GitHub Action.
