+[![Build Status](https://travis-ci.org/thomasnordquist/MQTT-Explorer.svg?branch=master)](https://travis-ci.org/thomasnordquist/MQTT-Explorer)
+
+### Version 0.0.9
+See the whole picture of your message queue.
+The perfect tool to integrate new services, IoT devices in your network.
+This application subscribes to all topics on your MQTT-Server and displays your message queue hierarchy, allowing you to drill-down to the topics that are of interest.
+
+## Download
+The app is prebuilt for Windows ([portable](https://github.com/thomasnordquist/MQTT-Explorer/releases/download/v0.0.9/MQTT-Explorer-0.0.9.exe), [installer](https://github.com/thomasnordquist/MQTT-Explorer/releases/download/v0.0.9/MQTT-Explorer-Setup-0.0.9.exe)), Linux ([AppImage](https://github.com/thomasnordquist/MQTT-Explorer/releases/download/v0.0.9/MQTT-Explorer-0.0.9-x86_64.AppImage)) and Mac ([dmg](https://github.com/thomasnordquist/MQTT-Explorer/releases/download/v0.0.9/MQTT-Explorer-0.0.9.dmg)).

+
+
+## Develop
+PRs and issues are welcome
+
+Install with `npm run install`, build with `npm run build`
+
+Start with `npm run start`
+
+The `app` directory contains all the rendering logic, the `backend` directory currently contains the models, tests, connection management.
+
+## License
+Not yet decided which license exactly, but the basic idea is: "You may do whatever you want with this tool, except sell it."
