+# PGPMailman plugin
+
+## Structure
+
+  * `pgpmailman` - A Core plugin.
+     - `styles` - Both styles generate a list keypair based on plugin settings on list creation as well as set other attributes for an encrypted mailing list.
+        - `EncryptedDefaultStyle`
+        - `EncryptedAnnounceStyle`
+
+     - `pgp` - Module that handles lower-level pgp related stuff. Such as the GPG keyrings, lookup of keys, encryption of messages, decryption, etc...
+
+     - `commands`
+        - `KeyEmailCommand` - Handles user key management through the `key` command.
+        - `KeyCLICommand`
+
+     - `runners`
+        - `EncryptedIncomingRunner` - Decrypts incoming messages for encrypted mailing lists and checks their signatures before passing them to the default IncomingRunner. Messages to ordinary lists are passed to the default IncomingRunner wthout change.
+        - `EncryptedOutgoingRunner` - Encrypts and optionally signs for configured lists. This is a runner and not a Pipeline since we need to encrypt all outgoing messages, so digests, virgin messages, posts...
+
+     - `archivers`
+        - `EncryptedHyperKittyArchiver` - Fetches list archive public keys from `pgphyperkitty`, uses them to send messages to archive encrypted, for encrypted lists.
+
+     - `initialize()` - A callable to be setup in a Mailman hook, to setup everything necessary for pgpmailman to run. Such as adding the `listname-key`@ subaddress, creating keyrings if not found, subscribing to events if necessary.
+
+
+## Instalation
+
+ * A setuptools package that needs to be installed into the same virtualenv as the Mailman 3 instance.
+
+## Configuration
+
+ * Custom runners, archivers and other site configuration options would need to be set.
