Describe the problem

Documentation for setting the public image directory is missing
Page is located here:
https://homarr.dev/docs/advanced/customizations/board-customization#background-image

The link to setting up the public image host is pointing to "link.to.something" which is invalid.

I'm not able to find what this should be looking at the various installation examples.
