+``@di.inject`` decorator can be used for making *inline* dependency injections.
 It *patches* decorated callable in such way that dependency injection will be
 done during every call of decorated callable.
 
-``@inject`` decorator takes only argument that is supposed to be an
-``dependency_injector.injections.KwArg`` injection.

-Any Python object will be injected *as is*, except *Dependency Injector* 
-providers, that will be called to provide injectable value.
+``@di.inject`` decorator takes keyword argument, that will be injected during 
+every next call of decorated callback with the same name. Any Python object 
+will be injected *as is*, except ``di.Provider``'s, which will be called to 
+provide injectable values.
