+If you edit Ruby files, you should run `rubocop` to verify:

 ### Styles
 
 Most style changes should be set in `assets/css/style.scss`. Some basic changes, like color variables, are set in the `_sass` directory. Please remember to consider multiple screen widths, printing (for relevant pages), and dark mode when changing or adding styles. You can see the defined colors [here](/docs/logos).
