 You can instrument your code with Powertools for AWS Lambda (TypeScript) 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 for AWS Lambda (TypeScript) 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](https://www.typescriptlang.org/docs/handbook/classes.html). 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.
