 ### Underscores
 
-When using properties, instance variables should always be accessed and mutated using `self.`. This means that all properties will be visually distinct, as they will all be prefaced with `self.`. Local variables should not contain underscores.
+When using properties, instance variables should always be accessed and mutated using `self.`. This means that all properties will be visually distinct, as they will all be prefaced with `self.`. 
 
 An exception to this: inside initializers, the backing instance variable (i.e. _variableName) should be used directly to avoid any potential side effects of the getters/setters.
 
+Local variables should not contain underscores.

 ## Methods
 
 In method signatures, there should be a space after the scope (-/+ symbol). There should be a space between the method segments (matching Apple's style).  Always include a keyword and be descriptive with the word before the argument which describes the argument.
