+## Instrumentation
+
+You can instrument your code with Powertools in three different ways:  
+
+* **Middy** middleware. It is the best choice if your existing code base relies on the [Middy](https://middy.js.org/docs/) middleware engine. Powertools offers compatible Middy middleware to make this integration seamless.
+* **Method decorator**. Use [TypeScript method decorators](https://www.typescriptlang.org/docs/handbook/decorators.html#method-decorators) if you prefer writing your business logic using TypeScript Classes. If you aren’t using Classes, this requires the most significant refactoring.
+* **Manually**. It provides the most granular control. It’s the most verbose approach, with the added benefit of no additional dependency and no refactoring to [TypeScript Classes](https://www.typescriptlang.org/docs/handbook/classes.html).
