-## Migration from Legacy System
+## Recent Updates (October 2025)
+
+### Czech Translation Completion ✅
+The Czech (`cs`) translation has been **fully completed** with comprehensive coverage:
+
+- **560+ translation keys** fully translated
+- **Professional quality** translations for humanitarian mapping context
+- **Complete GDPR compliance** in Czech language
+- **Validation guides** with detailed FAQ and instructions
+- **Mapathon materials** with hosting checklists and procedures
+- **Technical accuracy** for mapping terminology
+
+### Translation Quality Assurance
+- All translations maintain consistency with humanitarian mapping terminology
+- Czech translations include proper diacritics and grammar
+- Technical terms (OSM, JOSM, MapSwipe) appropriately localized
+- Cultural adaptation for Czech-speaking communities
+
+### Translation File Structure
+Each language file (`_data/{lang}.yml`) contains 560+ organized sections:
+```yaml
+# Image accessibility
+img-alt: { ... }           # 45+ image descriptions
+
+# Navigation and core content  
+nav: { ... }               # Menu structure
+banner: { ... }            # Homepage content
+how_we_work: { ... }       # Process explanations
+
+# Educational content

+advanced: { ... }          # JOSM and advanced mapping
+field: { ... }             # Field mapping guidance
+checker: { ... }           # Validation comprehensive FAQ
+
+# Event management
+host: { ... }              # Mapathon hosting guides
+events: { ... }            # Event management

+# GDPR compliance
+gdpr: { ... }              # Privacy policy, cookie consent
+
+# Blog and metadata
+blog: { ... }              # Blog navigation, pagination
+months: [ ... ]            # Date localization
+```
 
-The migration eliminated:
-- **52 duplicate English files** (moved to templates)
-- **4 language directories** (auto-generated now)
-- **Old locale detection logic** (replaced with Polyglot)
-- **Manual URL construction** (handled by plugin)
 
-### Benefits Achieved
-- 🚀 **80% reduction in code duplication**
-- 🔧 **Simplified maintenance** (single templates)
-- 🌐 **Consistent translation system**
-- ⚡ **Improved build performance**
-- 🧪 **Automated testing coverage**

+## Basic Development Workflow
 
-## Translation Syntax
-
-```liquid
-<!-- Set locale -->
-{% include get_locale.html %}
-
-<!-- Use translations -->
-<h1>{{site.data[locale].section.title}}</h1>
-<p>{{site.data[locale].section.text}}</p>
+### 1. Start Development
+```bash
+npm run serve               # Starts Jekyll + Gulp + Browsersync
+# Site available at: http://localhost:3000
 ```
 
-## Quick Tests
+### 2. Make Changes
+- Edit templates in `/app/`
+- Modify styles in `/app/assets/styles/`
+- Update scripts in `/app/assets/scripts/`
+- Auto-reload in browser when files change
 
+### 3. Test Changes
 ```bash
-# Verify all languages work
-for lang in "" "fr/" "es/" "cs/"; do
-  echo "${lang:-en}: $(grep 'feature-header' _site/${lang}about/index.html)"
-done
+npm test                    # Run full test suite
+./test-multilingual.sh     # Test translation system
+```
 
-# Check feed generation  
-ls _site/*/feed.xml _site/feed.xml
+### 4. Build for Production
+```bash
+npm run build              # Create optimized production build
 ```
 
-## Adding New Content
+## Troubleshooting
 
-1. **New page**: Create `newpage.html` in `/app/`
-2. **Add translations**: Update all `_data/{lang}.yml` files  
-3. **Test**: Run `./test-multilingual.sh`
+### Build Failures
+```bash
+# Clean and rebuild
+npm run clean && npm run serve
 
-## Common Patterns
+# Build with verbose output  
+bundle exec jekyll build --trace --verbose
 
-```yaml
-# _data/en.yml structure
-section:
-  title: "Section Title"
-  text: "Section content"
-  subsection:
-    item1: "First item"
-    item2: "Second item"
+# Check dependencies
+npm install && bundle install
 ```
 
-```liquid
-<!-- Template usage -->
-<h2>{{site.data[locale].section.title}}</h2>
-<p>{{site.data[locale].section.text}}</p>
-<ul>
-  <li>{{site.data[locale].section.subsection.item1}}</li>
-  <li>{{site.data[locale].section.subsection.item2}}</li>
-</ul>
-```
+### Server Issues
+- Use `http://localhost:3000` (Browsersync) not `http://127.0.0.1:4000` (Jekyll only)
+- Ensure both Node.js 20+ and Ruby 3.3+ are installed
+- Check that all dependencies are up to date
