 We can then instruct Nest to use the same singleton instance of `MyLogger` with the following construction:

 Finally, instruct Nest to use an instance of the custom logger in your `main.ts` file as shown below. Of course in this example, we haven't actually customized the logger behavior (by extending the `Logger` methods like `log()`, `warn()`, etc.), so this step isn't actually needed. But it **would** be needed if you added custom logic to those methods and wanted Nest to use the same implementation.
