   <p> If heart should <b>not</b> kill the Erlang runtime system, this can be indicated
-      using the environment variable <c><![CDATA[HEART_NO_KILL]]></c>. 
+      using the environment variable <c><![CDATA[HEART_NO_KILL=TRUE]]></c>.
       This can be useful if the command executed by heart takes care of this,
       for example as part of a specific cleanup sequence. 
-      If unset, the default behaviour will be to kill as described above.
+      If unset, or not set to <c><![CDATA[TRUE]]></c>, the default behaviour
+      will be to kill as described above.
