+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+[https://www.contributor-covenant.org/version/2/0/code_of_conduct.html][v2.0].

+# Contributing to Zigbee2MQTT
+
+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/guide/installation/01_linux.html) 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 your 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/advanced/support-new-devices/01_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/07-5123-06-zigbee-cluster-library-specification.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
