Installation
Before you add the plugin to calibre, you need to add the
KindleGen executable to the Kindle Comics Output plugin.
Since KindleGen is no longer supported
by Amazon, you need to download it from archive.org:
Extract the kindle_comics.zip and place the kindlegen.exe (Windows)
or kindlegen (Linux and macOS) into the Kindle Comics Output.zip file.
Then open calibre, go to Preferences > Plugins > Load plugin from file
and select Kindle Comics Input.zip and then Kindle Comics Output.zip.
