Kobo setup
Calibre will allow you to send ebooks to your Kobo without any configuration. However, the following plugins will enhance your experience.
KePub Metadata Reader / KePub Metadata Writer
These two plugins don't provide any features. They are just used as dependency by KePub Output and KoboTouch Extended.
KePub Output
Kobo readers are using Kepub files. Those are similar to standard Epub files but support additional functionalities.
This plugin allows conversion of ebooks to the kepub format.
