-# 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 see [MAINTAINERS.md](MAINTAINERS.md). 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 [http://contributor-covenant.org/version/1/4][version]

CONTRIBUTING.md

-# Contributing
-
-**Thank you for your interest in making the project better and more useful.
-Your contributions are highly welcome.**
-
-There are multiple ways of getting involved:
-
-- [Report a bug](#report-a-bug)
-- [Suggest a feature](#suggest-a-feature)
-- [Contribute code](#contribute-code)
-
-Below are a few guidelines we would like you to follow.
-If you need help, please reach out to us by opening an issue.
-
-## Report a bug
-
-Reporting bugs is one of the best ways to contribute. Before creating a bug
-report, please check that an [issue](/issues) reporting the same problem does
-not already exist. If there is such an issue, you may add your information as a
-comment.
-
-To report a new bug you should open an issue that summarizes the bug and set
-the label to "bug".
-
-If you want to provide a fix along with your bug report: That is great! In this
-case please send us a pull request as described in section [Contribute
-Code](#contribute-code).
-
-## Suggest a feature
-
-To request a new feature you should open an [issue](../../issues/new) and
-summarize the desired functionality and its use case. Set the issue label to
-"feature".
-
-## Contribute code
-
-This is an outline of what the workflow for code contributions looks like
-
-- Check the list of open [issues](../../issues). Either assign an existing
-  issue to yourself, or create a new one that you would like work on and
-  discuss your ideas and use cases.
-
-It is always best to discuss your plans beforehand, to ensure that your
-contribution is in line with our goals.
-
-- Fork the repository on GitHub
-- Create a topic branch from where you want to base your work. This is usually master.
-- Open a new pull request, label it `work in progress` and outline what you will be contributing
-- Make commits of logical units.
-- Make sure you sign-off on your commits `git commit -s -m "adding X to change Y"`
-- Write good commit messages (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- As you push your changes, update the pull request with new infomation and tasks as you complete them
-- Project maintainers might comment on your work as you progress
-- When you are done, remove the `work in progess` label and ping the maintainers for a review
-- Your pull request must receive a :thumbsup: from two [maintainers](MAINTAINERS)
-
-Thanks for your contributions!
-
-### Commit messages
-
-Your commit messages ideally can answer two questions: what changed and why.
-The subject line should feature the “what” and the body of the commit should
-describe the “why”.
-
-When creating a pull request, its description should reference the corresponding issue id.
-
-### Sign your work / Developer certificate of origin
-All contributions (including pull requests) must agree to the Developer
-Certificate of Origin (DCO) version 1.1. This is exactly the same one created
-and used by the Linux kernel developers and posted on
-http://developercertificate.org/. This is a developer's certification that he
-or she has the right to submit the patch for inclusion into the project. Simply
-submitting a contribution implies this agreement, however, please include a
-"Signed-off-by" tag in every patch (this tag is a conventional way to confirm
-that you agree to the DCO) - you can automate this with a [Git
-hook](https://stackoverflow.com/questions/15015894/git-add-signed-off-by-line-using-format-signoff-not-working)
-
-```
-git commit -s -m "adding X to change Y"
-```
-
-
-
-
-**Have fun, and happy hacking!**
