This is the site for www.kavitareader.com.
This has a few functions for the kavita application.
If you have a weblink that does not have a favicon in Kavita, you can upload it here and link it in /assets/favicons/urls.txt. Please upload everything through tinypng to reduce the size and keep the size around 32x32.
Kavita also has the ability to use Publisher images. You can upload your own in assets/publishers/publishers.txt. See the readme in that folder (about.txt) to understand the syntax.
