-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation
-in our community a harassment-free experience for everyone, regardless
-of age, body size, visible or invisible 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.
-
-We pledge to act and interact in ways that contribute to an open,
-welcoming, diverse, inclusive, and healthy community.
-
-## 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 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
-
-Community leaders 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.
-
-Community leaders 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 our community include using an
-official e-mail address, posting via an official social media account,
-or acting as an appointed representative at an online or offline
-event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior
-may be reported to the community leaders responsible for enforcement
-at our Discord channel. All complaints
-will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and
-security of the reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders 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 community leaders,
-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.
