## Implementation Phases

### Phase 1: Repository Initialization (30 min)

**Step 1: Local Repository Setup**
```bash
# Initialize git repository
git init
git branch -M main

# Create essential files
touch README.md LICENSE .gitignore

# First commit
git add .
git commit -m "chore: initialize repository"
```

**Step 2: GitHub Repository Creation**
```bash
# Create on GitHub (via gh CLI)
gh repo create OWNER/REPO --public --source=. --remote=origin

# Or use GitHub web interface for more options
```

```

### Phase 5: Documentation Site (60 min)

**Option 1: Docsify (Recommended for simplicity)**

1. Create `docs/` directory structure:
```
docs/
├── index.html (Docsify config)
├── README.md (Home page)
├── _sidebar.md (Navigation)
├── guide/
│   ├── getting-started.md
│   └── advanced.md
└── reference/
    ├── api.md
    └── cli.md
```

2. `docs/index.html`:
```html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Project Documentation</title>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link rel="stylesheet" href="//cdn.jsdelivr.net/npm/docsify/lib/themes/vue.css">
</head>
<body>
  <div id="app"></div>
  <script>
    window.$docsify = {
      name: 'Project Name',
      repo: 'https://github.com/owner/repo',
      loadSidebar: true,
      subMaxLevel: 2,
      search: 'auto'
    }
  </script>
  <script src="//cdn.jsdelivr.net/npm/docsify/lib/docsify.min.js"></script>
  <script src="//cdn.jsdelivr.net/npm/docsify/lib/plugins/search.min.js"></script>
</body>
</html>
```

3. `docs/_sidebar.md`:
```markdown
- [Home](/)
- [Getting Started](guide/getting-started.md)
- [API Reference](reference/api.md)
```

**Option 2: Jekyll (GitHub Pages default)**

1. Create `_config.yml`:
```yaml
title: Project Documentation
description: Project description
theme: jekyll-theme-cayman
markdown: kramdown
```

2. Enable GitHub Pages in repository settings
3. Select source: `main` branch, `/docs` folder

**Option 3: MkDocs (Python-based, feature-rich)**

1. Install: `pip install mkdocs mkdocs-material`
2. Initialize: `mkdocs new .`
3. Configure `mkdocs.yml`
4. Build: `mkdocs build`
5. Deploy: `mkdocs gh-deploy`

### Phase 6: Badges & Metadata (15 min)

**Essential Badges:**
```markdown
[![Version](https://img.shields.io/github/v/release/OWNER/REPO)](https://github.com/OWNER/REPO/releases)
[![License](https://img.shields.io/github/license/OWNER/REPO)](LICENSE)
[![CI](https://github.com/OWNER/REPO/actions/workflows/ci.yml/badge.svg)](https://github.com/OWNER/REPO/actions)
[![Coverage](https://codecov.io/gh/OWNER/REPO/branch/main/graph/badge.svg)](https://codecov.io/gh/OWNER/REPO)
[![npm](https://img.shields.io/npm/v/@org/package)](https://www.npmjs.com/package/@org/package)
```

**Repository Topics:**
- Maximum 20 topics
- Use lowercase, hyphens for spaces
- Include: language, framework, use-case, industry
- Example: `typescript`, `api`, `mental-models`, `cognitive-framework`

**About Section:**
- Concise description (160 chars max)
- Include primary use case

## Best Practices

### Branch Protection Rules
```
Settings → Branches → Add rule

Branch name pattern: main

Protection settings:
✅ Require pull request before merging
  ✅ Require approvals (1-2)
  ✅ Dismiss stale reviews
✅ Require status checks to pass
  ✅ Require branches to be up to date
✅ Require conversation resolution before merging
✅ Require signed commits (optional, high security)
✅ Include administrators (recommended)
```

### Semantic Versioning
```
MAJOR.MINOR.PATCH (e.g., 2.1.3)

MAJOR: Breaking changes
MINOR: New features (backwards compatible)
PATCH: Bug fixes (backwards compatible)

Pre-release: 1.0.0-alpha.1, 1.0.0-beta.2, 1.0.0-rc.1
Build metadata: 1.0.0+20130313144700
```

### Commit Message Convention
```
<type>(<scope>): <subject>

<body>

<footer>

Types:
- feat: New feature
- fix: Bug fix
- docs: Documentation only
- style: Formatting, no code change
- refactor: Code change (neither fix nor feature)
- perf: Performance improvement
- test: Adding or updating tests
- chore: Maintenance (dependencies, config)
- ci: CI/CD changes

Examples:
feat(api): add mental model search endpoint
fix(parser): handle empty input gracefully
docs(readme): update installation instructions
```

### Release Process
```bash
# 1. Update version
npm version [patch|minor|major]

# 2. Update CHANGELOG.md
# Add new version section with changes

# 3. Commit changes
git add .
git commit -m "chore: release v1.2.0"

# 4. Create and push tag
git tag -a v1.2.0 -m "Release v1.2.0"
git push origin main --tags

# 5. GitHub Actions automatically creates release
# Or manually via gh CLI:
gh release create v1.2.0 --title "v1.2.0" --notes-file RELEASE_NOTES.md
```

## Common Pitfalls

### Pitfall 1: Incomplete .gitignore
**Problem:** Sensitive files or build artifacts committed  
**Solution:** Use gitignore.io templates, review before first commit

### Pitfall 2: No Branch Protection
**Problem:** Direct pushes to main, untested code in production  
**Solution:** Enable branch protection immediately after repo creation

### Pitfall 3: Unclear Contributing Guidelines
**Problem:** Poor quality PRs, inconsistent code style  
**Solution:** Detailed CONTRIBUTING.md with examples and linting automation

### Pitfall 4: Missing CI/CD
**Problem:** Broken code merged, manual deployment friction  
**Solution:** Set up basic CI before accepting first PR

### Pitfall 5: Stale Documentation
**Problem:** Docs out of sync with code  
**Solution:** Automate docs deployment, make docs updates part of PR checklist
