Set repository secrets + +Go to the _Secrets_ tab in your repository settings and create the following secrets: + +- `AOC_ENABLED`: This variable controls whether the workflow is enabled. Set it to `true` to enable the progress tracker. +- `AOC_USER_ID`: Go to [this page](https://adventofcode.com/settings) and copy your user id. It's the number behind the `#` symbol in the first name option. Example: `3031` +- `AOC_YEAR`: the year you want to track. Example: `2021` +- `AOC_SESSION`: an active session[^2] for the advent of code website. To get this, press F12 anywhere on the Advent of Code website to open your browser developer tools.
