+# Code of Conduct
+
+## Our Pledge
+
+As contributors and maintainers of this project, and in order to keep community open and welcoming, we ask to
+respect all community members.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+Core team members are responsible for clarifying and enforcing our standards of acceptable behavior and will take 
+appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Core team members 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, and will communicate reasons for 
+moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing
+the community in public spaces. Examples of representing a project or community include using an official e-mail
+address, 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 promptly and fairly.
+
+All core team members are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Core team members will follow these Community Impact Guidelines in determining the consequences for any action they
+deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in 
+the community.
+
+**Consequence**: A private, written warning from core team members, providing clarity around the nature of the violation
+and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including
+unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding
+interactions in community spaces as well as external channels like social media. Violating these terms may lead to 
+a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified
+period of time. No public or private interaction with the people involved, including unsolicited interaction with those
+enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate
+behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.
