+      By adding &sudo; before any command, you can run commands with elevated
+      permissions. In addition, you can run commands as another user and use
+      their environment variables. Using &sudo; helps you accomplish system
+      administration tasks without logging in as root. This section provides
+      examples of some common commands that often require administrative
+      privileges.
