+Anonymization
+^^^^^^^^^^^^^
+
+Anonymization is the process of removing identifying information from content
+to make it safer for sharing with others.  For example, an IP address can
+often be used to uniquely identify an entity.  Substituting all instances of
+a particular IP with the same dummy value would remove the identifying data
+without losing statistical accuracy.  **lnav** has built-in support for
+anonymization through the :code:`--anonymize` flag on the :code:`:write-*`
+collection of commands.  While the anonymization process should catch most
