The Amazon Kindle format is the proprietary eBook format used for the Amazon Kindle platform. Amazon used to use a dedicated format for this, but Kindle eBooks are now also standard ePub files with some special requirements imposed by Amazon.

The actual format is effectively identical to ePub, so the two formats share the same basic settings. You can configure these settings in Project Explorer: Configuration > Publishing Options > eBooks.
