+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Hugo-based static site blog (miti99.com) built with the hugo-theme-stack theme. The blog features Vietnamese content with a focus on technology newsletters, programming tutorials, and technical insights.
+
+## Development Commands
+
+### Build and Development
+- **Local development server**: `hugo server --gc`
+- **Production build**: `hugo --gc --minify`
+- **Development with theme debugging**: `cd themes/hugo-theme-stack && ./debug.sh`
+
+### Docker Commands
+- **Build image**: `docker build -t miti99-blog .`
+- **Run container**: `docker run -p 80:80 miti99-blog`
+
+## Content Structure
+
+### Blog Posts
+- Posts are located in `content/post/YYYY/MM/DD/index.md`
+- Each post follows Hugo front matter format with title, date, tags, and categories
+- Images and assets are stored alongside posts in `img/` subdirectories
+- Additional resources (PDFs, data files) stored in `doc/` and `data/` subdirectories
+
+### Newsletter Posts
+- Newsletter posts use a specific format with numbered titles (e.g., "Newsletter #26")
+- Always include "AI-Assisted" tag and "Newsletter" category
+- Content is written in Vietnamese with professional tone
+- Follow the structure defined in `.cursor/rules/newsletter_processor.mdc`
+
+### Content Creation Guidelines
+- Use Vietnamese language for main content
+- Keep technical terms in English when appropriate
+- Include relevant tags (max 5 per post)
+- Maintain consistent date format: YYYY-MM-DD
+- Store assets in appropriate subdirectories within post folders
+
+## Hugo Configuration

+### Key Configuration Files
+- `config/_default/hugo.yml` - Main Hugo configuration

+
+### Important Settings

+
+## Newsletter Processing Workflow
+
+The repository includes a Cursor rule for automated newsletter processing located in `.cursor/rules/newsletter_processor.mdc`. This rule:
+
+1. Processes URLs to create/update newsletter posts
+2. Removes tracking parameters from URLs
+3. Creates Vietnamese summaries of articles
+4. Maintains consistent formatting and structure
+5. Auto-increments newsletter numbers
+6. Handles date formatting and file organization
+
+When working with newsletter content, follow the established pattern and ensure compliance with the processing rules.
+
+## File Organization
+
+- `content/` - All markdown content and assets
+- `config/` - Hugo configuration files
+- `layouts/` - Custom layout overrides
+- `static/` - Static assets served at site root
+- `themes/hugo-theme-stack/` - Theme files (do not modify directly)
+- `public/` - Generated site output (ignored in development)
+
+## Deployment
+
+The site uses a multi-stage Docker build:
+1. Build stage using Hugo v0.140.2 to generate static files
+2. Runtime stage using nginx:alpine to serve content
+3. Final image exposes port 80 for web traffic
