+# Contributing to Miniflux
+
+This document outlines how to contribute effectively to Miniflux.
+
+## Philosophy
+
+Miniflux follows a **minimalist philosophy**. The feature set is intentionally kept limited to avoid bloatware. Before contributing, please understand that:
+
+- **Improving existing features takes priority over adding new ones**
+- **Quality over quantity** - well-implemented, focused features are preferred
+- **Simplicity is key** - complex solutions are discouraged in favor of simple, maintainable code
+
+## Before You Start
+
+### Feature Requests
+
+Before implementing a new feature:
+
+- Check if it aligns with Miniflux's philosophy
+- Consider if the feature could be implemented differently to maintain simplicity
+- Remember that developing software takes significant time, and this is a volunteer-driven project
+- If you need a specific feature, the best approach is to contribute it yourself
+
+### Bug Reports
+
+When reporting bugs:
+
+- Search existing issues first to avoid duplicates
+- Provide clear reproduction steps
+- Include relevant system information (OS, browser, Miniflux version)
+- Include error messages, screenshots, and logs when applicable
+
+## Development Setup
+
+### Requirements
+
+- **Git**
+- **Go >= 1.24**
+- **PostgreSQL**
+
+### Getting Started
+
+1. **Fork the repository** on GitHub
+2. **Clone your fork locally:**
+   ```bash
+   git clone https://github.com/YOUR_USERNAME/miniflux.git
+   cd miniflux
+   ```
+
+3. **Build the application binary:**
+   ```bash
+   make miniflux
+   ```
+
+4. **Run locally in debug mode:**
+   ```bash
+   make run
+   ```
+
+### Database Setup
+
+For development and testing, you can run a local PostgreSQL database with Docker:
+
+```bash
+# Start PostgreSQL container
+docker run --rm --name miniflux2-db -p 5432:5432 \
+  -e POSTGRES_DB=miniflux2 \
+  -e POSTGRES_USER=postgres \
+  -e POSTGRES_PASSWORD=postgres \
+  postgres
+```
+
+You can also use an existing PostgreSQL instance. Make sure to set the `DATABASE_URL` environment variable accordingly.
+
+## Development Workflow
+
+### Code Quality
+
+1. **Run the linter:**
+   ```bash
+   make lint
+   ```
+   Requires `staticcheck` and `golangci-lint` to be installed.
+
+2. **Run unit tests:**
+   ```bash
+   make test
+   ```
+
+3. **Run integration tests:**
+   ```bash
+   make integration-test
+   make clean-integration-test
+   ```
+
+### Building
+
+- **Current platform:** `make miniflux`
+- **All platforms:** `make build`
+- **Specific platforms:** `make linux-amd64`, `make darwin-arm64`, etc.
+- **Docker image:** `make docker-image`
+
+### Cross-Platform Support
+
+Miniflux supports multiple architectures. When making changes, ensure compatibility across:
+- Linux (amd64, arm64, armv7, armv6, armv5)
+- macOS (amd64, arm64)
+- FreeBSD, OpenBSD, Windows (amd64)
+
+## Pull Request Guidelines
+
+### What Is Preferred
+
+✅ **Good Pull Requests:**
+
+- Focus on a single issue or feature
+- Include tests for new functionality
+- Maintain or improve performance
+- Follow existing code style and patterns
+- The commit messages follow the [conventional commit format](https://www.conventionalcommits.org/) (e.g., `feat: add new feature`, `fix: resolve bug`)
+- Update documentation when necessary
+
+### What to Avoid
+
+❌ **Pull Requests That Cannot Be Accepted:**
+
+- **Too many changes** - makes review difficult
+- **Breaking changes** - disrupts existing functionality
+- **New bugs or regressions** - reduces software quality
+- **Unnecessary dependencies** - conflicts with minimalist approach
+- **Performance degradation** - slows down the software
+- **Poor-quality code** - hard to maintain
+- **Dependent PRs** - creates review complexity
+- **Radical UI changes** - disrupts user experience
+- **Conflicts with philosophy** - doesn't align with minimalist approach
+
+### Pull Request Template
+
+When creating a pull request, please include:
+
+- **Description:** What does this PR do?
+- **Motivation:** Why is this change needed?
+- **Testing:** How was this tested?
+- **Breaking Changes:** Are there any breaking changes?
+- **Related Issues:** Link to any related issues
+
+## Code Style
+
+- Follow Go conventions and best practices
+- Use `gofmt` to format your Go code, and `jshint` for JavaScript
+- Write clear, descriptive variable and function names
+- Include comments for complex logic
+- Keep functions small and focused
+
+## Testing
+
+### Unit Tests
+- Write unit tests for new functions and methods
+- Ensure tests are fast and don't require external dependencies
+- Aim for good test coverage
+
+### Integration Tests
+- Add integration tests for new API endpoints
+- Tests run against a real PostgreSQL database
+- Ensure tests clean up after themselves
+
+## Communication
+
+- **Discussions:** Use GitHub Discussions for general questions and community interaction
+- **Issues:** Use GitHub issues for bug reports and feature requests
+- **Pull Requests:** Use PR comments for code-specific discussions
+- **Philosophy Questions:** Refer to the FAQ for common questions about project direction
+
+## Questions?
