-# 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 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 info@victoriametrics.com. All
-complaints will be reviewed and investigated and will result in a response that
-is deemed necessary and appropriate for 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.

-# Кодекс Поведения участника
-
-## Наши обязательства
-
-Мы, как участники, авторы и лидеры обязуемся сделать участие в сообществе
-свободным от притеснений для всех, независимо от возраста, телосложения,
-видимых или невидимых ограничений способности, этнической принадлежности,
-половых признаков, гендерной идентичности и выражения, уровня опыта,
-образования, социо-экономического статуса, национальности, внешности,
-расы, религии, или сексуальной идентичности и ориентации.
-
-Мы обещаем действовать и взаимодействовать таким образом, чтобы вносить вклад в открытое,
-дружелюбное, многообразное, инклюзивное и здоровое сообщество.

-
-* Проявление доброты и эмпатии к другим участникам проекта
-* Уважение к чужой точке зрения и опыту
-* Конструктивная критика и принятие конструктивной критики
-* Принятие ответственности, принесение извинений тем, кто пострадал от наших ошибок

-
-* Использование выражений или изображений сексуального характера и нежелательное сексуальное внимание или домогательство в любой форме
-* Троллинг, оскорбительные или уничижительные комментарии, переход на личности или затрагивание политических убеждений
-* Публичное или приватное домогательство
-* Публикация личной информации других лиц, например, физического или электронного адреса, без явного разрешения
-* Иное поведение, которое обоснованно считать неуместным в профессиональной обстановке
-
-## Обязанности
-
-Лидеры сообщества отвечают за разъяснение и применение наших стандартов приемлемого
-поведения и будут предпринимать соответствующие и честные меры по исправлению положения
-в ответ на любое поведение, которое они сочтут неприемлемым, угрожающим, оскорбительным или вредным.
-
-Лидеры сообщества обладают правом и обязанностью удалять, редактировать или отклонять
-комментарии, коммиты, код, изменения в вики, вопросы и другой вклад, который не совпадает
-с Кодексом Поведения, и предоставят причины принятого решения, когда сочтут нужным.
-
-## Область применения
-
-Данный Кодекс Поведения применим во всех во всех публичных физических и цифровых пространства сообщества,
-а также когда человек официально представляет сообщество в публичных местах.
-Примеры представления проекта или сообщества включают использование официальной электронной почты,
-публикации в официальном аккаунте в социальных сетях,
-или упоминания как представителя в онлайн или оффлайн мероприятии.
-
-## Приведение в исполнение
-
-О случаях домогательства, а так же оскорбительного или иного другого неприемлемого
-поведения можно сообщить ответственным лидерам сообщества с помощью письма на info@victoriametrics.com
-Все жалобы будут рассмотрены и расследованы оперативно и беспристрастно.
-
-Все лидеры сообщества обязаны уважать неприкосновенность частной жизни и личную
-неприкосновенность автора сообщения.
-
-## Руководство по исполнению
-
-Лидеры сообщества будут следовать следующим Принципам Воздействия в Сообществе,
-чтобы определить последствия для тех, кого они считают виновными в нарушении данного Кодекса Поведения:
-
-### 1. Исправление
-
-**Общественное влияние**: Использование недопустимой лексики или другое поведение,
-считающиеся непрофессиональным или нежелательным в сообществе.
-
-**Последствия**: Личное, письменное предупреждение от лидеров сообщества,
-объясняющее суть нарушения и почему такое поведение
-было неуместно. Лидеры сообщества могут попросить принести публичное извинение.
-
-### 2. Предупреждение
-
-**Общественное влияние**: Нарушение в результате одного инцидента или серии действий.
-
-**Последствия**: Предупреждение о последствиях в случае продолжающегося неуместного поведения.
-На определенное время не допускается взаимодействие с людьми, вовлеченными в инцидент,
-включая незапрошенное взаимодействие
-с теми, кто обеспечивает соблюдение Кодекса. Это включает в себя избегание взаимодействия
-в публичных пространствах, а так же во внешних каналах,
-таких как социальные сети. Нарушение этих правил влечет за собой временный или вечный бан.
-
-### 3. Временный бан
-
-**Общественное влияние**: Серьёзное нарушение стандартов сообщества,
-включая продолжительное неуместное поведение.
-
-**Последствия**: Временный запрет (бан) на любое взаимодействие
-или публичное общение с сообществом на определенный период времени.
-На этот период не допускается публичное или личное взаимодействие с людьми,
-вовлеченными в инцидент, включая незапрошенное взаимодействие
-с теми, кто обеспечивает соблюдение Кодекса.
-Нарушение этих правил влечет за собой вечный бан.
-
-### 4. Вечный бан
-
-**Общественное влияние**: Демонстрация систематических нарушений стандартов сообщества,
-включая продолжающееся неуместное поведение, домогательство до отдельных лиц,
-или проявление агрессии либо пренебрежительного отношения к категориям лиц.
-
-**Последствия**: Вечный запрет на любое публичное взаимодействие с сообществом.
-

CONTRIBUTING.md

@@ -1,16 +0,0 @@
-If you like VictoriaMetrics and want to contribute, then we need the following:
-
-- Filing issues and feature requests [here](https://github.com/VictoriaMetrics/VictoriaMetrics/issues).
-- Spreading a word about VictoriaMetrics: conference talks, articles, comments, experience sharing with colleagues.
-- Updating documentation.
-
-We are open to third-party pull requests provided they follow [KISS design principle](https://en.wikipedia.org/wiki/KISS_principle):
-
-- Prefer simple code and architecture.
-- Avoid complex abstractions.
-- Avoid magic code and fancy algorithms.
-- Avoid [big external dependencies](https://medium.com/@valyala/stripping-dependency-bloat-in-victoriametrics-docker-image-983fb5912b0d).
-- Minimize the number of moving parts in the distributed system.
-- Avoid automated decisions, which may hurt cluster availability, consistency or performance.
-
-Adhering `KISS` principle simplifies the resulting code and architecture, so it can be reviewed, understood and verified by many people.
