-A two or three letter prefix should always be used for class names and constants, however may be omitted for Core Data entity names. For any official raywenderlich.com books, starter kits, or tutorials, the prefix 'RW' should be used.
+A three letter prefix should always be used for class names and constants, however may be omitted for Core Data entity names. For any official raywenderlich.com books, starter kits, or tutorials, the prefix 'RWT' should be used.
 
 Constants should be camel-case with all words capitalized and prefixed by the related class name for clarity.

 ## Private Properties
 
-Private properties should be declared in class extensions (anonymous categories) in the implementation file of a class. Named categories (such as `RWPrivate` or `private`) should never be used unless extending another class. The Anonymous category can be shared/exposed for testing using the <headerfile>+Private.h file naming convention.
