-\noindent\\The executable \texttt{MongoTool} command line parameters are described in Table \ref{tab:mongo_tool_opts}.  \texttt{MongoTool} can be used

+\subsection{MongoDB Secure Usage Pattern}
+
+Many applications that use databases deploy the runtime application with a user account that does
+not have administrative privileges.  Using a non-administrative user in the configured
+\hyperref[sec:mongo_config]{MongoDB connection URL} may be desired to limit the capability
+of the CxAnalytix MongoDB user if the credentials are somehow exposed. Using \texttt{MongoTool},
+these steps can be followed to configure CxAnalytix to access MongoDB with a minimally privileged
+user account:
+
+\begin{enumerate}
+    \item Using the \texttt{-u} or \texttt{--url} option, provide the MongoDB connection
+    URL to \texttt{MongoTool} that contains the administrative account and password.
+    This allows \texttt{MongoTool} to create collections and users with the appropriate roles.
+
+    \item Provide the \texttt{----mongo-user} and \texttt{--mongo-password} options
+    to \texttt{MongoTool}.  These are the credentials for a minimally-privileged user
+    that will be created as part of the MongoDB schema creation.
+
+    \item Configure the \hyperref[sec:mongo_config]{MongoDB connection URL} with the
+    user credentials for the minimally-privileged user created by \texttt{MongoTool}.
+\end{enumerate}
