    Running the installation script <filename>unaccent.sql</> creates a text
    search template <literal>unaccent</> and a dictionary <literal>unaccent</>
-   based on it, with default parameters.  You can alter the
-   parameters, for example
+   based on it.  The <literal>unaccent</> dictionary has the default
+   parameter setting <literal>RULES='unaccent'</>, which makes it immediately
+   usable with the standard <filename>unaccent.rules</> file.
+   If you wish, you can alter the parameter, for example
 
 <programlisting>
 mydb=# ALTER TEXT SEARCH DICTIONARY unaccent (RULES='my_rules');
