 ## Quick start
 
-Jackfruit processes annotations on Java interfaces to generate code that can read and write Apache Configuration files.  The `demo` module includes sample code.  In the top level directory, run `mvn clean package`, which will build the annotation library, run the annotation processor on the file `demo/src/main/java/jackfruit/demo/DemoConfig.java`, and generate the class `demo/target/generated-sources/annotations/jackfruit/demo/DemoConfigFactory.java`.  The file `demo/src/main/java/jackfruit/demo/JackfruitDemo.java` shows some simple examples of use.

 ## Supported Annotations
 
-The `@Jackfruit` annotation goes on the interface.  The remaining annotations are for use on the interface methods.
+The `@Jackfruit` annotation goes on the abstract type.  The remaining annotations are for use on methods.
 
 ### Jackfruit
-This annotation goes on the interface to signify that it should be run through the annotation processor.  There is an optional "prefix" argument that can be used to add a prefix to all of the configuration keys created by the processor.

 ### Comment
