 Use this context argument to deploy a supplementary Streamlit app and its supporting cloud services, such as an [Amazon ECS](https://aws.amazon.com/ecs/) cluster. **Note:** This option builds a container image in your execution environment, e.g. your local machine. You can install e.g. docker for that.

 ### Strealit HTTPS Support
@@ -89,21 +89,21 @@ cdk deploy --context acm_certificate_arn=$ACM_CERT_ARN
 To add support for an authenticated user you must use the `email_address` flag which will deploy an [Amazon Cognito](https://aws.amazon.com/cognito/) user pool which sits in front of the application. A user will be created in the user pool and password distributed via email for you to login.
 
 ```
-$ cdk deploy --context email_address=$EMAIL_ADDRESS
+cdk deploy --context email_address=$EMAIL_ADDRESS
 ```
 
 ### Strealit Custom Domain Name
 
 If you would like to add a custom domain name in front of the application you must specify the `domain_name` argument. This will allow Cognito hosts to recognise the domain when authenticating. Once you have deployed with this flag you will need to apply any DNS records resolving to this domain.
 
 ```
-$ cdk deploy --context domain_name=$DOMAIN_NAME
+cdk deploy --context domain_name=$DOMAIN_NAME
 ```
 
 ### Supporting Multiple Arguments
 
 To support multiple arguments you simply append the `--context` flags after the previous argument. Please see the example below.
 
 ```
-$ cdk deploy --context aacm_certificate_arn=$ACM_CERT_ARN --context email_address=$EMAIL_ADDRESS --context domain_name=$DOMAIN_NAME
+cdk deploy --context aacm_certificate_arn=$ACM_CERT_ARN --context email_address=$EMAIL_ADDRESS --context domain_name=$DOMAIN_NAME
