+
+
+Interactive Mode 
+-----------------
+
+In interactive mode, `wavinfo` will present a command prompt which allows you
+to query the files provided on the command line and explore the metadata tree 
+interactively. Each file on the command line is scanned and presented as a 
+tree of metadata records.
+
+Commands include:
+
+``ls``
+    List the available metadata keys at the current level.
+
+``cd``
+    Traverse to a metadata key in the current level (or enter `..` to go up 
+    to the prevvious level).
+
+``bye``
+    Exit to the shell.
+
+Type `help` or `?` at the prompt to get a full list of commands.
 
 
 Example Output
 --------------
 
+.. attention::
+
+   Metadata fields containing binary data, such as the Broadcast-WAV UMID, will 
+   be included in the JSON output as a base-64 encoded string, preceded by the
+   marker "base64:".
