 Notes
 =====
 
+Collaboration
+    The encryption of the manifest is updated for each push to match the
+    participant configuration. Each pushing user must have the public
+    keys of all collaborators and correct participant config. You can
+    commit a keyring to the repo; further key management features do not
+    yet exist.
+
+Dependencies
+    ``rsync`` and ``curl`` for remotes ``rsync:`` and ``sftp:``
+    respectively. The main executable is a script for any
+    POSIX-compliant shell supporting ``local``.
+
+GNU Privacy Guard
+    GPG 1.4 or 2 are both supported. You need a configured personal
+    keypair. GPG configuration applies to algorithm choices for
+    public-key encryption, symmetric encryption, and signing. See
+    ``man gpg`` for more information.

+Remote ID
+    The generated Remote ID is not secret, it only exists to ensure that
+    two repositories signed by the same user can be distinguished.  You
