 This repository provides [Bun](https://bun.sh/) as an AWS Lambda runtime layer. It enables running JavaScript and TypeScript applications on AWS Lambda using Bun.
 
-> [!NOTE]
+> [!TIP]
 > This is Bun itself packaged as a Lambda layer, not the special Lambda runtime layer that Bun provides. If you need that layer, you can find instructions over at [oven-sh/bun/packages/bun-lambda](https://github.com/oven-sh/bun/tree/main/packages/bun-lambda)
 
 ## Available Layers
