-
-## 🎯 Quick Start Guide
-
-Want to get up and running immediately? Follow these steps:
-
-```bash
-# 1. Navigate to new site
-cd /home/user/behitek.github.io/new-site
-
-# 2. Install dependencies (will install Astro, TailwindCSS, etc.)

-
----
-
-## 🐛 Common Issues & Solutions
-
-### Issue: Images not loading
-**Solution**: Check that image paths use `/images/img/...` not `/img/...`
-
-### Issue: Dark mode not persisting
-**Solution**: Check browser localStorage, clear cache and reload
-
-### Issue: Blog post not showing
-**Solution**: Verify frontmatter has all required fields (title, date, description, language, category)
-
-### Issue: Build errors
-**Solution**: Run `npm run astro check` to see TypeScript errors
-
-### Issue: Port 4321 already in use
-**Solution**: Kill existing process or use `npm run dev -- --port 3000`
