 ## Features
 
-* [Tracing](./core/tracer) - Decorators and utilities to trace Lambda function handlers, and both synchronous and asynchronous functions
-* [Logging](./core/logger) - Structured logging made easier, and decorator to enrich structured logging with key Lambda context details
-* [Metrics](./core/metrics) - Custom Metrics created asynchronously via CloudWatch Embedded Metric Format (EMF)
-* [Bring your own middleware](./utilities/middleware_factory) - Decorator factory to create your own middleware to run logic before, and after each Lambda invocation
-* [Parameters utility](./utilities/parameters) - Retrieve parameter values from AWS Systems Manager Parameter Store, AWS Secrets Manager, or Amazon DynamoDB, and cache them for a specific amount of time
