+# 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, gender identity and expression, level of experience, 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 github@wassim.app. The project team will review and investigate all complaints, and will respond in a way that it deems 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 [http://contributor-covenant.org/version/1/4][version]

+# Contributing guidelines
+
+tl;dr: Contributions to this repository follow the same general guidelines as the Angular organization.
+
+As a contributor, here are the guidelines we would like you to follow:
+
+* [Code of Conduct](#coc)
+* [Issues and Bugs](#issue)
+* [Feature Requests](#feature)
+* [Coding Rules](#rules)
+* [Git Workflow (AKA Branching/Merging Strategy)](#commit)
+* [Commit Message Guidelines](#commit)
+* [Signing the CLA](#cla)
+
+## <a name="coc"></a> Code of Conduct
+
+Please read and follow our [Code of Conduct][coc].
+
+## <a name="issue"></a> Found a Bug?
+
+If you find a bug in the source code, you can help us by
+[submitting an issue](#submit-issue) to our [GitHub Repository][github]. Even better, you can
+[submit a Pull Request](#submit-pr) with a fix.
+
+## <a name="feature"></a> Missing a Feature?
+
+You can _request_ a new feature by [submitting an issue](#submit-issue) to our GitHub
+Repository. If you would like to _implement_ a new feature, please submit an issue with
+a proposal for your work first, to be sure that we can use it.
+Please consider what kind of change it is:
+
+* For a **Major Feature**, first open an issue and outline your proposal so that it can be
+  discussed. This will also allow us to better coordinate our efforts, prevent duplication of work,
+  and help you to craft the change so that it is successfully accepted into the project.
+* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
+
+## <a name="gitflow"></a> Git Workflow (AKA branching/merging strategy)
+
+To take full advantage of [semantic release](https://github.com/semantic-release/semantic-release), we use [Git Flow](http://nvie.com/posts/a-successful-git-branching-model/) as branching strategy. This means that PR must start from and be submitted to  `develop` branch.
+
+We do `git rebase` (instead of `git merge`) as merging strategy.
+
+
+## <a name="commit"></a> Commit Message Guidelines
+
+We have very precise rules over how our git commit messages can be formatted. This leads to **more
+readable messages** that are easy to follow when looking through the **project history**. But also,
+we use the git commit messages to **generate the change log**.
+
+### Commit Message Format
+
+Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
+format that includes a **type**, a **scope** and a **subject**:
+
+```
+<type>(<scope>): <subject>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+The **header** is mandatory and the **scope** of the header is optional.
+
+Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
+to read on GitHub as well as in various git tools.
+
+The footer should contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages/) if any.
+
+Samples: (even more [samples](https://github.com/manekinekko/angular-search-experience/commits/master))
+
+```
+docs(changelog): update changelog to beta.5
+```
+
+```
+fix(release): need to depend on latest rxjs and zone.js
+
+The version in our package.json gets copied to the one we publish, and users need the latest of these.
+```
+
+### Revert
+
+If the commit reverts a previous commit, it should begin with `revert:`, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
+
+### Type
+
+Must be one of the following:
+
+* **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
+* **ci**: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
+* **docs**: Documentation only changes
+* **feat**: A new feature
+* **fix**: A bug fix
+* **perf**: A code change that improves performance
+* **refactor**: A code change that neither fixes a bug nor adds a feature
+* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+* **test**: Adding missing tests or correcting existing tests
+
+### Scope
+
+The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages.
+
+### Subject
+
+The subject contains a succinct description of the change:
+
+* use the imperative, present tense: "change" not "changed" nor "changes"
+* don't capitalize the first letter
+* no dot (.) at the end
+
+### Body
+
+Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
+The body should include the motivation for the change and contrast this with previous behavior.
+
+### Footer
+
+The footer should contain any information about **Breaking Changes** and is also the place to
+reference GitHub issues that this commit **Closes**.
+
+**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
+
+A detailed explanation can be found in this [document][commit-message-format].
