 Several converter implementations are provided in the `core.convert.support` package as
 a convenience. These include converters from Strings to Numbers and other common types.

+For most use cases, the `convert` method specifying the _targetType_ can be used but it
+will not work with more complex types such as a collection of a parameterized element.
+If you want to convert a `List` of `Integer` to a `List` of `String` programmatically,
+for instance, you need to provide a formal definition of the source and target types.
+
+Fortunately, `TypeDescriptor` provides various options to make that straightforward:

+----
+	DefaultConversionService cs = new DefaultConversionService();
+
+	List<Integer> input = ....
+	cs.convert(input,
+		TypeDescriptor.forObject(input), // List<Integer> type descriptor
+		TypeDescriptor.collection(List.class, TypeDescriptor.valueOf(String.class)));
+----
+
+Note that `DefaultConversionService` registers converters automatically which are
+appropriate for most environments. This includes collection converters, scalar
+converters, and also basic `Object` to `String` converters. The same converters can
+be registered with any `ConverterRegistry` using the _static_ `addDefaultConverters`
+method on the `DefaultConversionService` class.
+
+Converters for value types will be reused for arrays and collections, so there is
+no need to create a specific converter to convert from a `Collection` of `S` to a
+`Collection` of `T`, assuming that standard collection handling is appropriate.
