+With the help of a static credentials provider your application can use a fixed set of AWS credentials. For that, you need
 to instantiate the `StaticCredentialsProviderBuilder` class and provide it with the AWS credentials. The following code
 snippet demonstrates how to set up an MQTT3 connection using static AWS credentials for SigV4-based authentication.
 
 ```typescript

 ### MQTT over WebSockets with Custom Authorizer
 
 An MQTT3 direct connection can be made using a [Custom Authorizer](https://docs.aws.amazon.com/iot/latest/developerguide/custom-authentication.html).

-
-```sh
-npm install
-node dist/index.js --endpoint <endpoint> \
---ca_file <file> \
---signing_region <signing region> \
---custom_auth_username <username> \
---custom_auth_authorizer_name <authorizer name> \
---custom_auth_password <password> \

 If your custom authorizer uses signing, you must specify the three signed token properties as well. It is your responsibility
 to URI-encode the username, authorizerName, and tokenKeyName parameters.
