-At runtime (normally during app startup), get or create an instance of `CassandraMutagen`. (It's easy to use [Nu](https://github.com/congainc/conga-nu) to get an instance by calling `$(CassandraMutagen.class)`. Note that the instance returned by Nu is client-managed, i.e. not a singleton, so be sure to hold onto it as long as you're using it.)
+At runtime (normally during app startup), get or create an instance of `CassandraMutagen`. You can use Nu, Guice, or another dependency injection framework, or if you really want, you can create an instance the old fashioned way: `new CassandraMutageImpl()`.
 
 Call `CassandraMutagen.initialize()` and provide the package name containing your mutations. You should see log messages listing all the resources that were found.
