# AWS CDK API Reference

## What is the AWS CDK

The AWS Cloud Development Kit (CDK) is a framework for defining cloud infrastructure as code and provisioning it through AWS CloudFormation. Instead of writing YAML or JSON templates by hand, you write ordinary code, in TypeScript, Python, Java, C#, or Go, and the CDK synthesizes it into CloudFormation templates behind the scenes. This site documents every construct, class, interface, and enum available for that code: what it does, what it takes, and how it fits together, with a working example on every page.

## Getting started

New to the CDK? The [Getting Started guide](https://docs.aws.amazon.com/cdk/v2/guide/getting-started.html) walks you through installing the CDK CLI, creating your first app in any of the five supported languages (TypeScript, Python, Java, C#, or Go), and deploying it. The [CDK Workshop](https://cdkworkshop.com) is a longer, hands-on tutorial if you want to build something real before diving into the reference.

Once your project is set up, use this site as your reference. Signatures, property names, and examples on construct pages are shown in whichever language you pick with the language switcher in the navigation bar.
