Add link and note to icons to nova docs

[tomhatzer]

Thank you once again for getting me the information about the used icons in nova, @themsaid !

It would be great if others could also profit from this information, so why not add it to the nova docs?

For everyone interested, the used icons are the Heroicons by @sschoger : https://github.com/sschoger/heroicons-ui

Have a great day!

Can you share here for us ?

@cloudstudio The link at the end of my first post above yours is the one that‘s taking you to the repository with the icons 😊👍🏻
