+SSH Envoy
+=========
+
+Provides for an easier use of [SSH][1] by setting up [ssh-agent][2], using the [envoy][3] service for systemd.
+
+Settings
+--------
+
+### Identities
+
+To load multiple identities, add the following line to *zpreztorc*:
+
+    zstyle ':prezto:module:ssh-envoy:load' identities 'id_rsa' 'id_dsa' 'id_github'
+
+If new identities are added while the agent is running, they will be added on your next login/source.
+
+Authors
+-------
+
+*The authors of this module should be contacted via the [issue tracker][4].*
