+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, 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.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers 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, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at <louis.grenard@gmail.com>. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+# Contributing
+
+Thanks a lot for your interest in contributing to Leon! :heart:
+
+**Leon needs open-source to live**, the more modules he has, the more skillful he becomes.
+
+**Before submitting your contribution**, please take a moment to review this document.
+
+Please note we have a [code of conduct](https://github.com/leon-ai/leon/blob/develop/.github/CODE_OF_CONDUCT.md), please follow it in all your interactions with the project.
+
+## How You Can Help
+
+Here are few examples about how you could help on Leon, by:
+
+- [Creating a new module](https://docs.getleon.ai/packages-modules.html).
+- [Working on new features](https://roadmap.getleon.ai) (what is in backlog or todo).
+- [Suggesting new ideas](https://github.com/leon-ai/leon/issues/new/choose).
+- [Reporting a bug](https://github.com/leon-ai/leon/issues/new?labels=bug&template=BUG.md).
+- [Improving the documentation](https://github.com/leon-ai/docs.getleon.ai) (translations, typos, better writing, etc.).
+- [Buying me a fruit juice](https://donate.getleon.ai).
+
+
+## Pull Requests
+
+**Working on your first Pull Request?** You can learn how from this *free* series [How to Contribute to an Open Source Project on GitHub](https://egghead.io/series/how-to-contribute-to-an-open-source-project-on-github).
+
+- **Please first discuss** the change you wish to make via [issue](https://github.com/leon-ai/leon/issues),
+email, or any other method with the owners of this repository before making a change.
+It might avoid a waste of your time.
+- The `master` branch is actually used as a snapshot of the latest stable release. **Do not submit your PRs
+against the `master` branch**.
+- Ensure your code **respect our coding standards** (cf. [.eslintrc.json](https://github.com/leon-ai/leon/blob/develop/.eslintrc.json)).
+To do so, you can run:
+
+  ```sh
+  npm run lint
+  ```
+- Make sure your **code passes the tests**. You can run the tests via the following command:
+  
+  ```sh
+  npm test
+  ```
+  
+  If you're adding new features to Leon, please include tests.
+  
+## Development Setup
+
+- Follow the [basic setup](https://github.com/leon-ai/leon/blob/develop/README.md#getting-started).
+- Then:
+
+  ```sh
+  # run development server
+  npm run dev:server
+  
+  # run development web app
+  npm run dev:app
+  
+  # run the wake word node (optional)
+  npm run wake
+  ```
+
+## Versioning
+
+- We use [Semantic Versioning](https://semver.org) for releases.
+- A new Leon module creation increases the MINOR version number of its relevant Leon package.
+- Each time a MAJOR or MINOR version number of a Leon package is increased, then the MINOR version number of the project should also be increased.
+- Each time a PATCH version number of a Leon package is increased, then the PATCH version number of the projet should also be increased.
+
+## Commits
+
+The commit message guideline is adapted from the [AngularJS Git Commit Guidelines](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#-git-commit-guidelines).

+
+## Introduction
+
+Leon is an **open-source personal assistant** who can live **on your server**.
+
+He **does stuff** when you **ask for it**.
+
+You can **talk to him** and he can **talk to you**.
+You can also **text him** and he can also **text you**.
+If you want to, Leon can communicate with you by being **offline to protect your privacy**.
+
+### Why?
+> 1. If you are a developer (or not), you may want to build many things that could help in your daily life.
+> Instead of building a dedicated project for each of those ideas, Leon can help you with his
+> packages/modules (skills) structure.
+> 2. With this generic structure, everyone can create his own modules and share them with others.
+> Therefore there is only one core (to govern all of them).
+> 3. Leon uses AI concepts, which is cool.
+> 4. Privacy matters, you can configure Leon to talk with him offline. You can already text with him without any third party services.
+> 5. Open-source is great.
+
+### What is this repository for?
+> This repository contains the following nodes of Leon:
+> - The server
+> - The packages/modules
+> - The web app
+> - The hotword node
+
+Sounds good for you? Then let's get started!

+# Hotword
+
+This node enables the wake word "Leon". Once this is running, you can
+call Leon by saying his name according to the language you chose.
+## Getting Started
+
+Please use **Node.js 8.x** here.
+
+Tips: use [nvm](https://github.com/creationix/nvm) to easily manage your Node.js versions.
+
+### Installation
+
+```sh
+# Install
+npm run setup:offline-hotword
+```
+
+### Usage
+
+```sh
+# From the project root:
+
+# Run main server
+npm run build && npm start
+
+# Go to http://localhost:1337
+
+# Run hotword node
+npm run wake
+
+# Say "Leon" via your microphone
+# Triggered!
+```
