## Deployment Instructions

1. Create a new directory, navigate to that directory in a terminal and clone the GitHub repository:
    ```bash
    git clone https://github.com/aws-samples/serverless-patterns
    ```
2. Change directory to the pattern directory its source code folder:
    ```bash
      cd apigw-to-private-apig-cdk/src
    ```
3. From the command line, use npm to install the development dependencies:
    ```bash
      npm install
    ```
4. To deploy from the command line use the following:
    ```bash
      npx cdk bootstrap aws://accountnumber/region
      npx cdk deploy --app 'ts-node .' --all
    ```
