+## 🔧 Migration Template
+
+For each post, use this format:
+
+```markdown
+---
+title: "[TITLE FROM ABOVE]"
+description: "[DESCRIPTION FROM OLD POST]"
+date: [DATE FROM ABOVE]
+author: "Hieu Nguyen"
+language: "[en or vi]"
+category: "[CATEGORY FROM ABOVE]"
+tags: [TAGS FROM ABOVE]
+image: "[IMAGE FROM ABOVE]"
+draft: false
+---
+
+[CONTENT - Remove frontmatter, remove <!--truncate-->, fix image paths]
+```
+
+---
+
+## 📋 Quick Migration Steps
+
+### For Each Post:
+
+1. **Read the original post**:
+   ```bash
+   cat /home/user/behitek.github.io/blog/2024-11-17-flux-lora.md
+   ```
+
+2. **Extract content** (skip frontmatter lines 1-8, remove truncate tag):
+   ```bash
+   sed '1,8d' blog/FILE.md | sed 's|<!--truncate-->||g' | sed 's|/img/blog|/images/blog|g'
+   ```
+
+3. **Create new MDX file** in:
+   ```
+   /home/user/behitek.github.io/new-site/src/content/blog/[slug].mdx
+   ```
+
+4. **Add proper frontmatter** using template above
+
+5. **Paste content** below frontmatter
+
+---
+
+## 🚀 Bulk Migration Script
+
+You can also use this command to help with extraction:
+
+```bash
+#!/bin/bash
+cd /home/user/behitek.github.io
