+# 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
+contato@evolution-api.com.
+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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.

+
+  ```bash
+  cd frontend
+  pnpm dev
+  # Frontend: http://localhost:3000
+  ```
+
+---
+
+## 📝 Issue and Pull Request Guidelines
+
+* **Check for existing issues** before creating a new one.
+* **Describe bugs or feature requests** clearly with steps to reproduce (if applicable).
+* **Pull Requests** should:
+
+  * Reference relevant issues (e.g., `Fixes #123`)
+  * Focus on one change at a time
+  * Include tests where applicable
+  * Pass linting and formatting checks
+
+---
+
+## 🧑‍💻 Code Standards
+
+* **All code comments, docstrings, and log messages must be in English**
+* **Variable, function, and class names**: English only
+* **API error messages and documentation**: English
+* **Commit messages**: English and follow [Conventional Commits](https://www.conventionalcommits.org/)
+
+  * Example: `feat(auth): add password reset functionality`
+* **Indentation**: 4 spaces
+* **Max line length**: 79 characters
+
+---
+
+## 📂 Project Structure and Best Practices
+
+* Follow the directory structure and naming conventions described in `.cursorrules`.
+* **Tests** should be placed under `tests/` and follow the `test_*` naming convention.
+* All routes require input validation using Pydantic schemas.
+* Use transactions for database operations affecting multiple records.
+* Document all public functions and classes.
+* Keep `.env.example` updated when adding environment variables.
+* Sensitive values must be set via environment variables and never hard-coded.
+
+---
+
+## 🐳 Docker Development
+
+* **Build and start stack:**
+
+  ```bash
+  make docker-build
+  make docker-up
+  ```
+* **Seed database:**
+
+  ```bash
+  make docker-seed
+  ```
+* **Stop stack:**
+
+  ```bash
+  make docker-down
+  ```

+# Next.js Project Rules
+
+## Language
+- All code, comments, documentation, commits, and PRs MUST be written in English.
+
+## Architecture
+
+### Folder Structure
+- `/app`: App router pages and API routes
+  - Route-specific components should be placed in their respective route folders
+- `/components`: Reusable UI components
+  - `/ui`: Shadcn UI components and their derivatives
+- `/contexts`: React Context providers
+- `/hooks`: Custom React hooks
+- `/lib`: Utility functions and configuration
+- `/public`: Static assets
+- `/services`: API service functions
+- `/styles`: Global styles
+- `/types`: TypeScript type definitions
+
+### Component Guidelines
+- Use functional components with TypeScript
+- Use the `.tsx` extension for React components
+- Follow a logical naming convention:
+  - Complex components: Use PascalCase and create folders with an index.tsx file
+  - Simple components: Single PascalCase named files
+
+### State Management
+- Use React Context for global state
+- Use React hooks for local state
+- Avoid prop drilling more than 2 levels deep
+
+### API & Data Fetching
+- Use API service modules in `/services` directory
+- Implement proper error handling and loading states
+- Use React Query or SWR for complex data fetching where appropriate
+
+## Development Patterns
+
+### Code Quality
+- Maintain type safety - avoid using `any` type
+- Write self-documenting code with descriptive names
+- Keep components focused on a single responsibility
+- Extract complex logic into custom hooks
+- Follow DRY (Don't Repeat Yourself) principle
+
+### CSS & Styling
+- Use Tailwind CSS for styling
+- Use Shadcn UI components as base building blocks
+- Maintain consistent spacing and sizing
+
+### Performance
+- Avoid unnecessary re-renders
+- Optimize images and assets
+- Implement code splitting where appropriate
+- Use dynamic imports for large components/pages
+
+### Testing
+- Write tests for critical business logic
+- Test components in isolation
+- Implement end-to-end tests for critical user flows
+
+## Git Workflow
+
+### Branch Naming
+- Features: `feature/short-description`
+- Bugfixes: `fix/short-description`
+- Hotfixes: `hotfix/short-description`
+- Releases: `release/version`
+
+## Conventions
+- Variable and function names in English
+- Log and error messages in English
+- Documentation in English
+- User-facing content (emails, responses) in English
+- Indentation with 4 spaces
+- Maximum of 79 characters per line
+
+## Commit Rules
+- Use Conventional Commits format for all commit messages
+- Format: `<type>(<scope>): <description>`
+- Types:
+  - `feat`: A new feature
+  - `fix`: A bug fix
+  - `docs`: Documentation changes
+  - `style`: Changes that do not affect code meaning (formatting, etc.)
+  - `refactor`: Code changes that neither fix a bug nor add a feature
+  - `perf`: Performance improvements
+  - `test`: Adding or modifying tests
+  - `chore`: Changes to build process or auxiliary tools
+- Scope is optional and should be the module or component affected
+- Description should be concise, in the imperative mood, and not capitalized
+- Use body for more detailed explanations if needed
+- Reference issues in the footer with `Fixes #123` or `Relates to #123`
+- Examples:
+  - `feat(auth): add password reset functionality`
+  - `fix(api): correct validation error in client registration`
+  - `docs: update API documentation for new endpoints`
+  - `refactor(services): improve error handling in authentication`
+
+Format: `type(scope): subject`
+
+Examples:
+- `feat(auth): add login form validation`
+- `fix(api): resolve user data fetching issue`
+- `docs(readme): update installation instructions`
+- `style(components): format according to style guide`
+
+### Pull Requests
+- Keep PRs focused on a single feature or fix
+- Include descriptive titles and descriptions
+- Reference related issues
+- Request code reviews from appropriate team members
+- Ensure CI checks pass before merging
+
+## Code Review Guidelines
+- Focus on code quality, architecture, and maintainability
+- Provide constructive feedback
+- Address all review comments before merging
+- Maintain a respectful and collaborative tone
