+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make 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 within all project spaces, and it also
+applies when an individual is representing the project or its community
+in public spaces. 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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor
+Covenant](https://www.contributor-covenant.org), version 1.4, available
+at
+<https://www.contributor-covenant.org/version/1/4/code-of-conduct.html>

+## Pull Requests
+
+Pull requests are a great way to get your ideas into this repository.
+
+Before opening a pull request, reach out to one of the organization
+members or state your intent in the [discord server](https://discord.com/invite/JrG4kPrF8v). This prevents you
+from potentially doing redundant or low-priority work. 
+
+When deciding if I merge in a pull request I look at the following
+things:
+
+### Does it state intent
+
+You should be clear which problem you're trying to solve with your
+contribution.
+
+For example:
+
+> Add link to code of conduct in README.md
+
+Doesn't tell me anything about why you're doing that
+
+> Add link to code of conduct in README.md because users don't always
+> look in the CONTRIBUTING.md
+
+Tells me the problem that you have found, and the pull request shows me
+the action you have taken to solve it.
+
+### Is it of good quality
+
+- There are no spelling mistakes
+- It reads well
+- For english language contributions: Has a good score on
+  [Grammarly](https://www.grammarly.com) or [Hemingway
+  App](https://www.hemingwayapp.com/)
+
+### Does it move this repository closer to my vision for the repository
+
+The aim of this repository is:
+
+- To provide a distributed (primarily) in-memory data cache that is
+  embeddable in Go and compatible with RESP.
+- Foster a culture of respect and gratitude in the open source
+  community.
+
+### Does it follow the contributor covenant
+
+This repository has a [code of conduct](CODE_OF_CONDUCT.md), I will
+remove things that do not respect it.
+
+If all the above conditions are met, feel free to fork the project
+and open a pull request.
