 When defining services, you'll usually want to be able to access these definitions
 within your application code. These services are called ``public``. For example,

-However, there are use-cases when you don't want a service to be public. This
-is common when a service is only defined because it could be used as an

+In some cases, a service *only* exists to be injected into another service

 However, if a service has been marked as private, you can still alias it (see
 below) to access this service (via the alias).
