# Quick Reference Guide

## Adding Content

### Add a New Page Section

```bash
mkdir -p content/mysection
echo "# My Section Title" > content/mysection/index.md
echo "Your content here..." >> content/mysection/index.md
```

Visit: `http://your-site/mysection`

### Add a Blog Post

```bash
echo "# Blog Post Title" > content/blog/my-post-slug.md
echo "Post content..." >> content/blog/my-post-slug.md
```

Visit: `http://your-site/blog/my-post-slug`

### Edit Content

Just edit the markdown file - changes appear immediately!

```bash
nano content/home/index.md
# Changes visible at http://your-site/
```

## Testing

### Run Tests

```bash
php test.php
```

### Check Setup

```bash
# All required files exist?
ls -la lib/ partials/ js/
ls -la .htaccess router.php template.php

# Content structure?
find content -name "*.md"

# Comrak installed?
comrak --version
```

## Troubleshooting

### 404 errors on every page

1. Check `.htaccess` is enabled
2. Check content files exist: `ls content/home/index.md`
3. Check error log: `/var/log/apache2/error.log`

### Page shows but no sidebar links

1. Check `partials/sidebar.php` is loading
2. Check `content/*/` directories exist
3. Clear browser cache

### JavaScript not working smoothly

1. Open browser console (F12)
2. Check for JavaScript errors
3. **This is okay!** Site works without JS

### Adding content but it doesn't appear

1. Create file: `content/section/index.md`
2. Make sure first line is: `# Section Title`
3. Reload browser page
4. Check permissions: `ls -la content/section/`

## File Locations

| File | Purpose |
|------|---------|
| `index.php` | Entry point |
| `router.php` | Request routing |
| `template.php` | Base HTML layout |
| `lib/ContentRenderer.php` | Markdown → HTML |
| `lib/ContentManager.php` | Content discovery |
| `partials/sidebar.php` | Navigation menu |
| `partials/footer.php` | Footer |
| `js/enhance.js` | Progressive enhancement |
| `content/*/` | Your content (markdown) |
| `.htaccess` | URL rewriting |

## Common Tasks

### Update sidebar order

Edit `partials/sidebar.php` - change `$priority_sections`

### Change page layout

Edit `template.php` - modify HTML structure

### Add smooth page transitions

Already included in `js/enhance.js` - it's enabled by default!

### Disable JavaScript enhancement

Remove or comment out the `<script>` tag in `template.php`

### Enable caching

In `router.php`, change line:
```php
$renderer = new ContentRenderer(false);  // Change to: true
```

### Clear cache

In `router.php`:
```php
$renderer->clearCache();
```

## Command Reference

```bash
# Test everything
php test.php

# Generate sitemap (optional)
nu build.nu

# View error log
tail -f /var/log/apache2/error.log

# Check if comrak works
echo "# Test" | comrak --gfm

# Check PHP
php -v

# Restart Apache
sudo systemctl restart apache2
```

## URLs

| URL | Content | Source |
|-----|---------|--------|
| `/` | Home | `content/home/index.md` |
| `/projects` | Projects | `content/projects/index.md` |
| `/blog` | Blog listing | Auto-generated from `content/blog/*.md` |
| `/blog/post-slug` | Blog post | `content/blog/post-slug.md` |
| `/about` | About | `content/about/index.md` |
| `/custom-page` | Custom | `content/custom-page/index.md` |

## Performance

- **First request**: ~50ms (with comrak)
- **Subsequent requests**: <5ms (cached)
- **Page size**: 20-50KB (typical)
- **No build step**: Content appears instantly!

## Browser Support

- ✅ Chrome/Edge 90+
- ✅ Firefox 88+
- ✅ Safari 14+
- ✅ Works without JavaScript

## Security

- HTML output is rendered server-side
- Markdown is from trusted sources (you!)
- `--unsafe` flag in comrak allows HTML in markdown
- Basic XSS protection via `htmlspecialchars()` in sidebar

## Backup Strategy

```bash
# Backup content
tar -czf backup-content.tar.gz content/

# Backup everything
tar -czf backup-full.tar.gz .

# List what to back up
content/          # Your content
lib/              # Core libraries
```

## Migration from Old System

Old files still work but aren't used:
- `home/index.json` → Use `content/home/index.md`
- `blog/*.json` → Auto-generated from `content/blog/*.md`
- Old `index.php` → Now just includes `router.php`

**No need to delete old files** - they won't interfere.

## Next Steps

1. ✅ Test with `php test.php`
2. ✅ Visit your site in browser
3. ✅ Try adding a test page
4. ✅ Check error log for issues
5. ✅ Read `README_REFACTORING.md` for details
6. ✅ Archive old JSON files when confident
