 The easiest way will be for you to download the icon you want from the the [`icons`](./icons) directory. Simply find which macOS version you would like the icon for, and if applicable the light or dark mode variant, and download the `icns` file within that directory using GitHub's Download button once within a file's context:

 To apply the icon, right click on the directory that you wish to update the icon of and click 'Get Info', a new dialogue window should appear. You now need to click-and-drag the downloaded `icns` file into the small icon in the top left of the window next to the directory name:
