+description: |
+  A [Juju](https://juju.is/) [charm](https://juju.is/docs/olm/charmed-operators)
+  for deploying and managing [Hockeypuck](https://hockeypuck.io/) on Kubernetes. Hockeypuck is an
+  OpenPGP public keyserver tool used to manage public key infrastructure for PGP 
+  (Pretty Good Privacy). PGP is a system for securing communication through encryption and 
+  digital signatures.
+
+  The server provides interfaces to add, look up, replace and delete public keys from the 
+  keyserver. Hockeypuck can synchronize public key material with SKS (Synchronizing Key Server) 
+  and other Hockeypuck servers. It implements the HTTP Keyserver Protocol and the SKS database 
+  reconciliation protocol.
+
+  For DevOps and SRE teams, this charm will make operating Hockeypuck simple and straightforward
+  through Juju's clean interface.
