+# Yii Contributor Code of Conduct
+
+## Our Pledge
+
+As contributors and maintainers of this project, and in order to keep Yii community open and welcoming, we ask to respect all community members.
+
+## 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
+* Personal attacks
+* Trolling or insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic
+  addresses, 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 posting via an official social media account,
+within project GitHub, official forum or acting as an appointed representative at
+an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported
+by contacting core team members. 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 1.4.0, available at
+[http://contributor-covenant.org/version/1/4/][version]

+# Getting started
+
+Since Yii 3 consists of many packages, we have a [special development tool](https://github.com/yiisoft/docs/blob/master/005-development-tool.md).
+
+1. [Clone the repository](https://github.com/yiisoft/yii-dev-tool).
+
+2. [Set up your own fork](https://github.com/yiisoft/yii-dev-tool#using-your-own-fork).
+
+3. Now you are ready. Fork any package listed in `packages.php` and do `./yii-dev install username/package`.
+
+If you don't have any particular package in mind to start with:
+
+- [Check roadmap](https://github.com/yiisoft/docs/blob/master/003-roadmap.md).
+- Check package issues at github. Usually there are some.
+- Ask @samdark.
