+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
+====================
+
+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.
+
+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 Technical Advisory Board (TAB) at
+<tab@lists.linux-foundation.org>. All complaints will be reviewed and
+investigated and will result in a response that is deemed necessary and
+appropriate to the circumstances. The TAB is obligated to maintain
+confidentiality with regard to the reporter of an incident. Further details of
+specific enforcement policies may be posted separately.
+
+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, version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-Code of Conflict
-----------------
-
-The Linux kernel development effort is a very personal process compared
-to "traditional" ways of developing software. Your code and ideas
-behind it will be carefully reviewed, often resulting in critique and
-criticism. The review will almost always require improvements to the
-code before it can be included in the kernel. Know that this happens
-because everyone involved wants to see the best possible solution for
-the overall success of Linux. This development process has been proven
-to create the most robust operating system kernel ever, and we do not
-want to do anything to cause the quality of submission and eventual
-result to ever decrease.
-
-If however, anyone feels personally abused, threatened, or otherwise
-uncomfortable due to this process, that is not acceptable. If so,
-please contact the Linux Foundation's Technical Advisory Board at
-<tab@lists.linux-foundation.org>, or the individual members, and they
-will work to resolve the issue to the best of their ability. For more
-information on who is on the Technical Advisory Board and what their
-role is, please see:
-
- - http://www.linuxfoundation.org/projects/linux/tab
-
-As a reviewer of code, please strive to keep things civil and focused on
-the technical issues involved. We are all humans, and frustrations can
-be high on both sides of the process. Try to keep in mind the immortal
-words of Bill and Ted, "Be excellent to each other."
