Need help updating provider documentation. Where are updates to provider documentation located?

Technical details that need descriptions in the provider documentation include:

• "aws_role" parameter for OpenSearch provider in "pygeoapi-config.yml"
• AWS OpenSearch provider details for AWS SigV4 Token authentication.
• Some IAM Policy examples for the role and the OpenSearch service
