+### Example 3: Start a transcript file with a unique name and store it on a file share
+
+The following example creates a transcript file with a name unique enough to be stored on in a
+shared location. The filename is constructed from the user's name, the hostname of the computer
+running PowerShell, the version of PowerShell, and the date and time. The transcript is stored in
