 Adding registrations to an existing collection
 ----------------------------------------------
 
-In most cases you would register a collection with a single line of code. There are cases where you need to append registrations to an already registered collection. Common use cases for this are integration scenarios where you need to interact with some framework that made its own registrations on your behalf, or in cases where you want to add extra types based on configuration settings. In these cases it might be benifecial to append registrations to an existing collection.
