## 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]:
