Problem Description

The web-llm-chat repository currently lacks a CONTRIBUTING.md file, which makes it difficult for new contributors to understand:

• How to set up the development environment
• Code style and conventions to follow
• Testing requirements
• Pull request submission process
• Community guidelines and expectations

This creates friction for potential contributors and may lead to:

• ❌ Inconsistent code contributions
• ❌ PRs that don't follow project standards
• ❌ Increased review time for maintainers
• ❌ Lower contribution quality
• ❌ Missed opportunities for community growth

Proposed Solution

Create a comprehensive CONTRIBUTING.md file in the repository root with the following sections:

1. Getting Started

## Getting Started

### Prerequisites
- Node.js >= 18.x
- npm or yarn
- Git

### Development Setup
1. Fork the repository
2. Clone your fork: `git clone https://github.com/YOUR_USERNAME/web-llm-chat.git`
3. Install dependencies: `npm install`
4. Start dev server: `npm run dev`
5. Visit http://localhost:3000

2. Development Workflow

• Branch naming conventions (e.g., feature/, fix/, docs/)
• Commit message format (conventional commits)
• Testing requirements before submitting PR
• Code formatting (ESLint, Prettier)

3. Code Style Guidelines

• TypeScript best practices
• Component structure for React
• File organization patterns
• Naming conventions

4. Pull Request Process

## Submitting a Pull Request

1. Create a feature branch from `main`
2. Make your changes with clear, descriptive commits
3. Add tests if applicable
4. Ensure all tests pass: `npm test`
5. Update documentation if needed
6. Submit PR with detailed description
7. Link related issues using "Fixes #123" or "Relates to #123"
8. Wait for review and address feedback

5. Testing Guidelines

• How to run tests locally
• Writing unit tests
• Integration test requirements
• Test coverage expectations

6. Documentation

• When to update README.md
• JSDoc/TSDoc requirements
• Examples and code samples

7. Community Guidelines

• Code of Conduct reference
• Communication channels (Discord, GitHub Discussions)
• How to report bugs vs. feature requests
• Security vulnerability reporting

8. Issue Labels and Workflow

• Explanation of labels: bug, enhancement, good first issue, etc.
• Claiming issues before working on them
• Expected response times

Benefits

Adding a CONTRIBUTING.md file will:

✅ Lower the barrier to entry for new contributors
✅ Improve code quality through clear standards
✅ Reduce maintainer workload by setting expectations upfront
✅ Build a stronger community with clear communication
✅ Speed up PR reviews with consistent submissions
✅ Attract more contributors by being welcoming and organized
✅ Align with OSS best practices (standard for most major projects)

Examples from Similar Projects

Many successful open-source projects have comprehensive CONTRIBUTING.md files:

• Next.js CONTRIBUTING.md
• React CONTRIBUTING.md
• MLC-LLM CONTRIBUTING.md

Implementation Checklist

• Create CONTRIBUTING.md in repository root
• Include all sections outlined above
• Add link to CONTRIBUTING.md in README.md
• Update PR template to reference contribution guidelines
• Announce new guidelines in Discord/community channels

Additional Context

This would be especially helpful given:

1. Recent influx of issues like [Bug] chat.weblm.ai not loading LLMs #85 requiring community help
2. Growing interest in the project
3. Need for standardized contribution process
4. Active development and feature additions
