+      (description
+       "Technology for Resting Email Encrypted Storage (TREES) is a NaCL-based
+Dovecot encryption plugin.  This plugin adds individually encrypted mail
+storage to the Dovecot IMAP server.  It is inspired by Posteo's scrambler
+which uses OpenSSL and RSA keypairs.  TREES works in a similar way, but uses
+the Sodium crypto library (based on NaCL).
+
+How it works:
+@enumerate
+@item On IMAP log in, the user's cleartext password is passed to the plugin.
+@item The plugin creates an argon2 digest from the password.
+@item This password digest is used as a symmetric secret to decrypt a libsodium secretbox.
+@item Inside the secretbox is stored a Curve25519 private key.
+@item The Curve25519 private key is used to decrypt each individual message,
+using lidsodium sealed boxes.
+@item New mail is encrypted as it arrives using the Curve25519 public key.
+@end enumerate\n")
