+"""
+This plugin adds a :term:`/vcard` command to all tabs, allowing you to request
+and display the vcard-temp of any given entity.
+
+Command
+-------
+
+.. glossary::
+
+    /vcard
+
+        **Usage (globally):** ``/vcard <jid>``
+
+        **Usage (in a MUC tab):** ``/vcard <jid or nick>``
+
+        **Usage (in a conversation or roster tab):** ``/vcard [jid]``
+
+        Globally, you can do ``/vcard user@server.example`` to get a vcard.
+
+        In a MUC, you can either do it on a JID or a nick (``/vcard nick``,
+        ``/vcard room@muc.server.example/nick`` or ``/vcard
+        user@server.example``).
+
+        In a private or a direct conversation, you can do ``/vcard`` to request
+        vcard from the current interlocutor, and in the roster to do it on the
+        currently selected contact.
