+# 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 [email protected]. 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 to Magento 2 code
+
+Contributions to the Magento 2 codebase are done using the fork & pull model.
+This contribution model has contributors maintaining their own fork of the Magento 2 repository.
+The forked repository is then used to submit a request to the base repository to “pull” a set of changes.
+For more information on pull requests please refer to [GitHub Help](https://help.github.com/articles/about-pull-requests/).
+
+Contributions can take the form of new components or features, changes to existing features, tests, documentation (such as developer guides, user guides, examples, or specifications), bug fixes or optimizations.
+
+The Magento 2 development team or community maintainers will review all issues and contributions submitted by the community of developers in the first in, first out order.
+During the review we might require clarifications from the contributor.
+If there is no response from the contributor within two weeks, the pull request will be closed.
+
+For more detailed information on contribution please read our [beginners guide](https://github.com/magento/magento2/wiki/Getting-Started).
+
+## Contribution requirements
+
+1. Contributions must adhere to the [Magento coding standards](https://devdocs.magento.com/guides/v2.3/coding-standards/bk-coding-standards.html).
+2. Pull requests (PRs) must be accompanied by a meaningful description of their purpose. Comprehensive descriptions increase the chances of a pull request being merged quickly and without additional clarification requests.
+3. Commits must be accompanied by meaningful commit messages. Please see the [Magento Pull Request Template](https://github.com/magento/magento2/blob/2.3-develop/.github/PULL_REQUEST_TEMPLATE.md) for more information.
+4. PRs which include bug fixes must be accompanied with a step-by-step description of how to reproduce the bug.
+3. PRs which include new logic or new features must be submitted along with:
+* Unit/integration test coverage
+* Proposed [documentation](https://devdocs.magento.com) updates. Documentation contributions can be submitted via the [devdocs GitHub](https://github.com/magento/devdocs).
+4. For larger features or changes, please [open an issue](https://github.com/magento/magento2/issues) to discuss the proposed changes prior to development. This may prevent duplicate or unnecessary effort and allow other contributors to provide input.
+5. All automated tests must pass (all builds on [Travis CI](https://travis-ci.org/magento/magento2) must be green).
+
+## Contribution process
+
+If you are a new GitHub user, we recommend that you create your own [free github account](https://github.com/signup/free).
+This will allow you to collaborate with the Magento 2 development team, fork the Magento 2 project and send pull requests.
+
+1. Search current [listed issues](https://github.com/magento/magento2/issues) (open or closed) for similar proposals of intended contribution before starting work on a new contribution.
+2. Review the [Contributor License Agreement](https://magento.com/legaldocuments/mca) if this is your first time contributing.
+3. Create and test your work.
+4. Fork the Magento 2 repository according to the [Fork A Repository instructions](https://devdocs.magento.com/guides/v2.3/contributor-guide/contributing.html#fork) and when you are ready to send us a pull request – follow the [Create A Pull Request instructions](https://devdocs.magento.com/guides/v2.3/contributor-guide/contributing.html#pull_request).
+5. Once your contribution is received the Magento 2 development team will review the contribution and collaborate with you as needed.
+
