 Everybody is invited and welcome to contribute to Zigbee2MQTT. Zigbee2MQTT is writen in JavaScript and is based upon [zigbee-herdsman](https://github.com/koenkk/zigbee-herdsman) and [zigbee-herdsman-converters](https://github.com/koenkk/zigbee-herdsman-converters). Zigbee-herdsman-converters contains all device definition, zigbee-herdsman is responsible for handling all communication with the adapter.

 - Pull requests are always created against the [**dev**](https://github.com/Koenkk/zigbee2mqtt/tree/dev) branch.
- Easiest way to start developing Zigbee2MQTT is by setting up a development environment (aka bare-metal installation). You can follow this [guide](https://www.zigbee2mqtt.io/getting_started/running_zigbee2mqtt.html#running-zigbee2mqtt) to do this.
- You can run the tests locally by executing `npm test`. Zigbee2MQTT enforces 100% code coverage, in case you add new code check if you code is covered by running `npm run test-with-coverage`. The coverage report can be found under `coverage/lcov-report/index.html`. Linting is also enforced and can be run with `npm run eslint`.
- When you want to add support for a new devices no changes to Zigbee2MQTT have to be made, only to zigbee-herdsman-converters. You can find a guide for it [here](https://www.zigbee2mqtt.io/how_tos/how_to_support_new_devices.html).

 ### Internal Architecture
-Zigbee2MQTT is made up of three modules, each developed in its own Github project. Starting from the hardware (adapter) and moving up; [zigbee-herdsman](https://github.com/koenkk/zigbee-herdsman) connects to your Zigbee adapter an makes an API available to the higher levels of the stack. For e.g. Texas Instruments hardware, zigbee-herdsman uses the [TI zStack monitoring and test API](https://github.com/koenkk/zigbee-herdsman/raw/master/docs/Z-Stack%20Monitor%20and%20Test%20API.pdf) to communicate with the adapter. Zigbee-herdsman handles the core Zigbee communication. The module [zigbee-herdsman-converters](https://github.com/koenkk/zigbee-herdsman-converters) handles the mapping from individual device models to the Zigbee clusters they support. [Zigbee clusters](https://github.com/Koenkk/zigbee-herdsman/raw/master/docs/Zigbee%20Cluster%20Library%20Specification%20v7.pdf) are the layers of the Zigbee protocol on top of the base protocol that define things like how lights, sensors and switches talk to each other over the Zigbee network.  Finally, the Zigbee2MQTT module drives zigbee-herdsman and maps the zigbee messages to MQTT messages. Zigbee2MQTT also keeps track of the state of the system.  It uses a `database.db` file to store this state; a text file with a JSON database of connected devices and their capabilities.

Zigbee2MQTT provides a [web-based interface](https://github.com/nurikk/zigbee2mqtt-frontend) that allows monitoring and configuration.
+
+### Developing
+Zigbee2MQTT uses TypeScript (partially for now). Therefore after making changes to files in the `lib/` directory you need to recompile Zigbee2MQTT. This can be done by executing `npm run build`. For faster development instead of running `npm run build` you can run `npm run build-watch` in another terminal session, this will recompile as you change files.

 ## Supported devices
-See [Supported devices](https://www.zigbee2mqtt.io/information/supported_devices.html) to check whether your device is supported. There is quite an extensive list, including devices from vendors like Xiaomi, Ikea, Philips, OSRAM and more.
