-Load and run an .so library that implements `shuttle_service::Service`. 
+This will no loger load a `.so` will the code to start the runtime will be codegened for all services.
+An example can be found in `src/bin/rocket.rs` which contains the secrets rocket example at the bottom and the codegen at the top.
 
 To test, first start a provisioner from the root directory using:
 
 ```bash
 docker-compose -f docker-compose.rendered.yml up provisioner
 ```
