+### Locale
 
+This library supports all [Product Advertising API locales](http://docs.aws.amazon.com/AWSECommerceService/latest/DG/Locales.html) and you can set them using `SetLocale`:
+
+It defaults to US but to set the locale call `SetLocale()` __before__ calling the product methods. E.g.
+
+```php
+$amazonAPI->SetLocale('uk');
+```

+At this time, these are the current supported locales:
+
+* Brazil ('br')
 * Canada ('ca')
 * China ('cn')
-* Germany ('de')
-* Spain ('es')
 * France ('fr')

-The default is UK but to set the locale call `SetLocale()` __before__ calling the product methods. E.g.

+### SSL
 
 By default it will use HTTPS, but if you don't want to use SSL then call the following before using the product methods and it will connect to the HTTP endpoints:
 
-```
+```php
 $amazonAPI->SetSSL(false);
 ```
 
-**Note:** I have no idea why I originally had this method. Perhaps the Amazon Product API didn't use SSL at one point. I've enabled HTTPS as default now but you can turn it off if you need to. I assume you won't.

 #### Default sort
 
-By default, the `ItemSearch` method will search by featured. If you want to sort by another category then pass a 3rd parameter with the name of the category you wish to sort by. These differ by category type but the two you'll probably need are `price` (sort by price low to high) or `-price` (sort by price high to low). See [ItemSearch Sort Values](http://docs.aws.amazon.com/AWSECommerceService/latest/DG/APPNDX_SortValuesArticle.html) for more details.
