This package provides an Emacs interface for reading Mailman 3 archives hosted via Hyperkitty. To use it, you need to set `hyperkitty-mlists' variable to a list of pairs of Mailinglist and base url for the hyperkitty's hosted instance. For example: (setq hyperkitty-mlists ((cons "test@mailman3.org" "https://lists.mailman3.org/archives"))) Then, you can simply use `M-x hyperkitty' to start using.
