+# Code of Conduct
+
+As a community of developers, we strive to create a friendly, safe, and welcoming environment for
+all, regardless of experience level, gender, gender identity and expression, sexual orientation,
+disability, personal appearance, body size, race, ethnicity, age, religion, or nationality.
+
+## 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 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.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is
+representing the project or its community.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting
+the project team at [igor@katsuba.dev](mailto:igor@katsuba.dev) . All complaints will be reviewed
+and investigated and will result in a response that is deemed necessary and appropriate to the
+circumstances.
+

+[Contributor Covenant](https://www.contributor-covenant.org), version 2.0, available at

+# Coding Standards
+
+Welcome to the coding standards for the `mutates` project. This document outlines the guidelines and
+best practices for contributing to the codebase.
+
+## General Guidelines
+
+- **Consistency**: Ensure that your code is consistent with the existing codebase.
+- **Readability**: Write code that is easy to read and understand.
+- **Documentation**: Document your code where necessary, especially for complex logic.
+
+## Code Style
+
+- **Indentation**: Use 2 spaces for indentation.
+- **Line Length**: Limit lines to 100 characters.
+- **Quotes**: Use single quotes for strings.
+- **Semicolons**: Use semicolons at the end of statements.
+
+## TypeScript Specific
+
+- **Types**: Always define types for function parameters and return values.
+- **Interfaces**: Prefer interfaces over type aliases for object shapes.
+- **Enums**: Use enums for sets of related constants.
+
+## Example
+
+Here is an example of a well-formatted TypeScript function:
+
+```typescript
+function greet(name: string): string {
+  return `Hello, ${name}`;
+}
+```
+
+## Linting and Formatting
+
+We use ESLint and Prettier to enforce code style and formatting. Ensure that your code passes all
+linting checks before submitting a pull request.
+
+## Commit Messages
+
+Follow the [Conventional Commits](https://www.conventionalcommits.org/) specification for commit
+messages. This helps in automating the release process and generating changelogs.
+
+## Additional Resources
+
+For more detailed guidelines, refer to the following documents:
+
+- [Contribution Guide](/contribution-guide)
+- [Frequently Asked Questions](/frequently-asked-questions)
+- [Troubleshooting](/troubleshooting)
+
+Thank you for contributing to `mutates`!
