-Emitter is a real-time communication service for connecting online devices. Infrastructure and APIs for IoT, gaming, apps and real-time web. At its core, emitter.io is a distributed, scalable and fault-tolerant publish-subscribe messaging platform based on MQTT protocol and featuring message storage.
+# Emitter: Distributed Publish-Subscribe Platform
+
+Emitter is a distributed, scalable and fault-tolerant publish-subscribe  platform built with MQTT protocol and featuring message storage, security, monitoring and more:
+* **Publish/Subscribe** using MQTT over TCP or Websockets.
+* Resilient, **highly available and partition tolerant** (AP in CAP terms).
+* Able to handle **3+ million of messages/sec** on a single broker.
+* Supports **message storage** with history and **message-level expiry**.
+* Provides **secure channel keys** with permissions and can face the internet.
+* Automatic **TLS/SSL** and encrypted inter-broker communication.
+* Built-in **monitoring with Prometheus, StatsD** and more.
+* **Shared subscriptions, links** and private links for channels.
+* Easy **deployment with Docker and Kubernetes** of production-ready clusters.
 
 Emitter can be used for online gaming and mobile apps by satisfying the requirements for low latency, binary messaging and high throughput. It can also be used for the real-time web application such as dashboards or visual analytics or chat systems. Moreover, Emitter is perfect for the internet of things and allows sensors to be controlled and data gathered and analyzed.

-## Sandbox
-
-Emitter has a [sandbox](https://emitter.io/login) - a free cloud cluster which allows you to quickly try out the platform and see how simple it is to create connected, real-time applications. The movie below shows you how to create your sandbox account and create a simple hello-world application within **5 minutes**.

 ## Usage Example
 
 The code below shows a small example of usage of emitter with the Javascript SDK. As you can see, the API exposes straightforward methods such as `publish` and `subscribe` which can take binary payload and are secured through channel keys.
