+# 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
+
+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]. 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.
+

+# Support
+
+> This project has a [code of conduct](./CODE_OF_CONDUCT.md).
+> By interacting with this repository, organization, or community you agree to abide by its terms.
+
+Hi! :wave: We're excited that you're using this project and we’d love to help. To help us help you, please read through the following guidelines.
+
+Please understand that the people involved with this project often do so for fun, next to their day job; you are not entitled to free customer service.
+
+## Questions
+
+Help us help you!
+
+Spending time framing a question and adding support links or resources makes it much easier for us to help. It’s easy to fall into the trap of asking something too specific when you’re close to a problem. Then, those trying to help you out have to spend a lot of time asking additional questions to understand what you are hoping to achieve.
+
+Spending the extra time up front can help save everyone time in the long run.
+
+* Try to define what you need help with:
+  * Is there something in particular you want to do?
+  * What problem are you encountering and what steps have you taken to try and fix it?
+  * Is there a concept you’re not understanding?
+* Have you tried checking out the documentation?
+* Check out the tips on [requesting support](./CONTRIBUTING.md) in the contributing guide
+* The more time you put into asking your question, the better we can help you
+
+## Contributions
+
+See [CONTRIBUTING.md](./CONTRIBUTING.md) on how to contribute.
