+## Features
+
+The emulator includes the following core capabilities:
+
+- **Data Plane REST API**: Supports message-level operations, including Send, Receive, and Peek.
+- **Control Plane REST API**: Enables CRUD operations for namespaces and messaging entities (queues, topics, and subscriptions) via Azure Resource Manager (ARM).
+- **Multiple Authentication Modes**: Supports both Connection String and Managed Identity authentication.
+- **Containerized Deployment**: Runs as a lightweight, Linux-based Docker container.
+- **Cross-Platform Compatibility**: Fully compatible with Windows, macOS, and Linux environments.
+- **Flexible Configuration**: Manage Service Bus entities via the Service Bus Administration Client or through JSON-based configuration files.
+- **Advanced Streaming**: Supports message streaming via the Advanced Message Queuing Protocol (AMQP).
+
+## Limitations
+
+The current version of the emulator does **not** support the following:
+
+- **Protocols**: JMS protocol streaming and AMQP Web Sockets (AMQP over TCP is the only supported transport).
+- **Messaging Patterns**: Transactions, auto-forwarding (queue chaining), and message lock renewal.
+- **Validation**: Enforcements such as maximum entity counts or maximum message sizes.
+- **Metrics**: Property-based message counts for queues, topics, and subscriptions may be inaccurate.
+
+The following Azure-native features are currently unavailable in the emulator:
+
+- **Scaling & Resiliency**: Autoscale, Geo-disaster recovery, and Large Message support.
+- **Monitoring**: Visual metrics, alerts, and telemetry dashboards.
+
+## Samples
+
+Explore the following samples to get started with Service Bus on LocalStack:

+- [Azure Service Bus with Spring Boot](https://github.com/localstack/localstack-azure-samples/tree/main/samples/servicebus/java)
