        ## Example
        
        #### Connect to DynamoDB
        You can connect to DynamoDB by following any of these two ways.
        
        1. Using AWS config
        <!-- MARKDOWN-AUTO-DOCS:START (CODE:src=./examples/using-aws-config-to-connect-to-dynamodb.py) -->
        <!-- The below code snippet is automatically added from ./examples/using-aws-config-to-connect-to-dynamodb.py -->
        ```py
        from LucidDynamodb import DynamoDb
        db = DynamoDb()
        
        """
        $ pip install awscli  #can add user flag
        $ aws configure
        AWS Access Key ID [****************ABCD]:[enter your key here]
        AWS Secret Access Key [****************xyz]:[enter your secret key here]
        Default region name [us-west-2]:[enter your region here]
        Default output format [None]:
        """
        ```
        <!-- MARKDOWN-AUTO-DOCS:END -->
        
        2. Using AWS secret key
        <!-- MARKDOWN-AUTO-DOCS:START (CODE:src=./examples/using-aws-secret-to-connect-to-dynamodb.py) -->
        <!-- The below code snippet is automatically added from ./examples/using-aws-secret-to-connect-to-dynamodb.py -->
        ```py
        from LucidDynamodb import DynamoDb

        AWS_ACCESS_KEY_ID = os.getenv("AWS_ACCESS_KEY_ID")
        AWS_SECRET_ACCESS_KEY = os.getenv("AWS_SECRET_ACCESS_KEY")
        db = DynamoDb(region_name="us-east-1",
