If you want to add a link to the footer copyright, not just a text, you can customize it.

1. In your config.toml file, set the copyright param like this.

   1 2 3

   ... copyright = This is my {} copyright text ...

   The {} part will be your copyright link.

   You can use markdown syntax for a link.

   1 2 3

   ... copyright = [zzossig](https://zzossig.io) - All right reserved ...

2. In your params.toml file, set the copyrightOptions params

   1 2 3 4 5 6

   ... [copyrightOptions] enableCopyrightLink = false copyrightLink = "https://..." copyrightLinkImage = "https://..." copyrightLinkText = "copyright link text"

3. For example, I set this params like this.

   1 2 3 4 5 6

   ... [copyrightOptions] enableCopyrightLink = true copyrightLink = "http://creativecommons.org/licenses/by-sa/4.0/" copyrightLinkImage = "" copyrightLinkText = "CC BY-SA"
