-* 🧛 Vampire 🧛
-
-Vampire is a web based tool for collaborative creation of
-playlists. You can edit and arrange playlists in real time with your
-collaborators. It is meant to be self-hosted and shared by small
-groups of friends.
-
-Vampire was built with love in [[https://common-lisp.net/][Common Lisp]]. It uses the excellent [[https://github.com/rabbibotton/clog][CLOG]]
-system for its front end, and the easy-as-pie object prevelence system
-system [[https://github.com/sharplispers/bknr.datastore][BKNR.DATASTORE]] for its backend.
-
-To build and deploy, see the INSTALL file in this repository.
