# Adding the 'AWS CDK bootstrap' action
<a name="cdk-boot-action-add"></a>

 Use the following instructions to add the **AWS CDK bootstrap** action to your workflow. 

**Before you begin**

Before you can use the **AWS CDK bootstrap** action, make sure you have an AWS CDK app ready. The bootstrap action will synthesize the AWS CDK app before bootstrapping. You can write your app in any programming language supported by the AWS CDK.

Make sure your AWS CDK app files are available in:
+ A CodeCatalyst [source repository](source.md), or 
+ A CodeCatalyst [output artifact](workflows-working-artifacts.md) generated by another workflow action
