 === Managing Jetty Base and Jetty Home
 
 Instead of managing multiple Jetty implementations out of several different distribution locations, it is possible to maintain a separation between the binary installation of the standalone Jetty (known as `${jetty.home}`), and the customizations for your specific environment(s) (known as `${jetty.base}`).
+In addition to easy management of multiple server instances, is allows for quick, drop-in upgrades of Jetty.
 There should always only be *one* Jetty Home (per version of Jetty), but there can be multiple Jetty Base directories that reference it.

+It is important to remember that you should *not* modify the XML files in your `$JETTY_HOME`.
+If you do for some reason feel you want to change the way an XML file operates, it is best to make a copy of it in your `$JETTY_BASE` in an `/etc` directory.
+Jetty will always look first to the `$JETTY_BASE` for configuration.
