+# What's Maple?
+
+Maple is a Java [annotation processor](http://docs.oracle.com/javase/6/docs/technotes/guides/apt/index.html) for the generation of type-safe bean mapping classes.
+
+All you have to do is to define one more more mapper interfaces, annotate them with the `@Mapper` annotation and add the required mapping methods. During compilation, Maple will generate an implementation for each mapper interface, based on your preferred mapping framework (currently [Dozer](http://dozer.sourceforge.net/) is supported, more to come).
+
+The following shows an example. First, an object (e.g. a JPA entity) and an accompanying data transfer object (DTO):
+
+	public class Car {
+
+		private String make;
+		private int numberOfSeats;
+		private int yearOfManufacture;
+		
+		//constructor, getters, setters etc.
+	}
+	
+	public class CarDto {
+
+		private String make;
+		private int seatCount;
+		private int yearOfManufacture;
+
+		//constructor, getters, setters etc.
+	}
+	
+Both types are rather similar, only the seat count attributes have different names. The mapper interface thus looks like this:
+
+	@Mapper
+	public interface CarMapper {
+
+		CarMapper INSTANCE = Mappers.getMapper( CarMapper.class );
+
+		@Mapping(source = "numberOfSeats", target = "seatCount"),
+		CarDto carToCarDto(Car car);
+
+		Car carDtoToCar(CarDto carDto);
+	}
+	
+The interface is straight-forward: 
+
+* Annotating it with `@Mapper` let's the Maple processor kick in during compilation
+* The `INSTANCE` member provides access to the mapper implementation for clients (a service loader based alternative coming soon)
+* For each mapping direction (entity to DTO and vice versa) there is a conversion method. For those attributes which have differing names and thus can't be mapped automatically, a mapping is configured using the `@Mapping` annotation on one of the methods.
+
+Based on the mapper interface, clients can perform object mappings in a very easy and type-safe manner:
+
+	@Test
+	public void shouldMapCarToDto() {
+
+		//given
+		Car car = new Car( "Morris", 2, 1980 );
+
+		//when
+		CarDto carDto = CarMapper.INSTANCE.carToCarDto( car );
+
+		//then
+		assertThat( carDto ).isNotNull();
+		assertThat( carDto.getMake() ).isEqualTo( car.getMake() );
+		assertThat( carDto.getSeatCount() ).isEqualTo( car.getNumberOfSeats() );
+		assertThat( carDto.getyearOfManufacture() ).isEqualTo( car.getyearOfManufacture() );
+	}
+		
+Sometimes not only the names of two corresponding attributes differ, but also their types. This can be addressed by defining a custom type converter:
+
+	public class IntToStringConverter implements Converter<Integer, String> {
+
+		@Override
+		public String from(Integer source) {
+			return source != null ? source.toString() : null;
+		}
+
+		@Override
+		public Integer to(String target) {
+			return target != null ? Integer.valueOf( target ) : null;
+		}
+	}
+	
+To make use of a converter, specify its type within the `@Mapping` annotation:
+
+	@Mapper
+	public interface CarMapper {
+
+		CarMapper INSTANCE = Mappers.getMapper( CarMapper.class );
+
+		@Mappings({
+			@Mapping(source = "numberOfSeats", target = "seatCount"),
+			@Mapping(source = "yearOfManufacture", target = "manufacturingYear", converter = IntToStringConverter.class)
+		})
+		CarDto carToCarDto(Car car);
+
+		Car carDtoToCar(CarDto carDto);
+	}
+	
+# Using Maple
+
+Maple is a Java annotation processor based on [JSR 269](jcp.org/en/jsr/detail?id=269) and as such can be used within command line builds (javac, Ant, Maven etc.) as well as from within your IDE.
+
+Detailed instructions on the usage will be added soon, in between the [set up](http://docs.jboss.org/hibernate/stable/jpamodelgen/reference/en-US/html/chapter-usage.html) of the Hibernate JPA meta model generator can be used as general guideline for setting up an annotation processor.
+
+In order to use Maple, you have to check out its sources as it is currently not available in any public Maven repository.
+
+# What's next
+
+Maple is just in its very beginnings. There are several ideas for further features, including but not limited to:
+
+* Allow to generate mappers for several existing mapping frameworks (currently only Dozer is supported).
+* Generate "native" mappers, that is without any reflection, but by direcly invoking getters and setters within the generated mapper. This should deliver very efficient mapper implementations
+* Provide a way to access the underlying mapper in order to make use of advanced features not provided by the Maple API (similar to the `unwrap()` method of JPA etc.)
+* Provide a way to add custom mapping code in a very simple way:
+
+	@Mapper(extension=CarMapperCustomization.class)
+	public interface CarMapper {
+	
+		CarMapper INSTANCE = Mappers.getMapper( CarMapper.class );
+	
+		//automatically generated mapping methods
+		CarDto carToCarDto(Car car);
+
+		Car carDtoToCar(CarDto carDto);
+
+		//very complex mapping which requires some hand-coding
+		Vehicle carToVehicle(Car car);
+	}
+	
+	public abstract class CarMapperCustomization implements CarMapper {
+	
+		@Override
+		public Vehicle carToVehicle(Car car) {
+			//implement custom mapping logic
+		}
+	}
