+# LaTeX Preview System Setup Guide
+
+This guide will help you set up the LaTeX preview system for the C++ Qt Learning Book.
+
+## ๐ Quick Start
+
+### Option 1: Web Preview (Recommended)
+
+1. **Start the preview server:**
+ ```bash
+ # Windows
+ start-preview.bat
+
+ # Linux/macOS
+ ./start-preview.sh
+
+ # Or manually
+ python server.py
+ ```
+
+2. **Open your browser:**
+ - Go to `http://localhost:8000`
+ - You'll see the preview interface with build options
+
+3. **Build the document:**
+ - Click on any build option in the web interface
+ - The PDF will be generated in the `output/` directory
+ - Click "Open Book PDF" to view the result
+
+### Option 2: Command Line
+
+1. **Build the document:**
+ ```bash
+ # Simple build
+ make all
+
+ # Build with index
+ make index
+
+ # Build with bibliography
+ make bib
+
+ # Clean auxiliary files
+ make clean
+ ```
+
+2. **View the PDF:**
+ ```bash
+ # Open the PDF
+ make open
+
+ # Or manually open output/book.pdf
+ ```
+
+## ๐ Prerequisites
+
+### Required Software
+
+1. **Python 3.6+** (for the preview server)
+2. **LaTeX Distribution** (one of the following):
+ - **TeX Live** (recommended for Linux/macOS)
+ - **MiKTeX** (recommended for Windows)
+ - **MacTeX** (for macOS)
+
+### LaTeX Packages
+
+The following LaTeX packages are required:
+
+```bash
+# Ubuntu/Debian
+sudo apt-get install texlive-full texlive-latex-extra texlive-fonts-extra texlive-lang-indonesian texlive-bibtex-extra biber makeindex latexmk
+
+# macOS (with Homebrew)
+brew install --cask mactex
+
+# Windows
+# Install MiKTeX and ensure all packages are installed
+```
+
+## ๐ง Installation Steps
+
+### Step 1: Install LaTeX
+
+#### Windows
+1. Download and install MiKTeX from https://miktex.org/
+2. During installation, choose "Install missing packages on-the-fly = Yes"
+3. Add MiKTeX to your PATH environment variable
+
+#### macOS
+```bash
+# Using Homebrew
+brew install --cask mactex
+
+# Or download from https://www.tug.org/mactex/
+```
+
+#### Linux (Ubuntu/Debian)
+```bash
+sudo apt-get update
+sudo apt-get install texlive-full texlive-latex-extra texlive-fonts-extra texlive-lang-indonesian texlive-bibtex-extra biber makeindex latexmk
+```
+
+### Step 2: Install Python Dependencies
+
+```bash
+# The server uses only Python standard library
+# No additional packages required
+```
+
+### Step 3: Verify Installation
+
+```bash
+# Check LaTeX installation
+pdflatex --version
+
+# Check Python installation
+python --version
+
+# Test build
+make all
+```
+
+## ๐ณ Docker Alternative
+
+If you prefer using Docker:
+
+```bash
+# Start the Docker environment
+docker-compose up -d

+make index # Build with index
+make bib # Build with bibliography
+make clean # Clean auxiliary files
+make distclean # Clean everything including PDF
+make open # Open the generated PDF
+make watch # Watch for changes and rebuild
+make help # Show help message
+```
+
+### Using Build Script
+```bash
+./build-latex.sh # Build the complete document
+```
+
+### Manual LaTeX Commands
+```bash
+cd latex
+pdflatex -interaction=nonstopmode -output-directory=../output book.tex
+pdflatex -interaction=nonstopmode -output-directory=../output book.tex
+makeindex -o ../output/book.ind ../output/book.idx
+pdflatex -interaction=nonstopmode -output-directory=../output book.tex
+```
+
+## ๐ Troubleshooting
+
+### Common Issues
+
+1. **"pdflatex: command not found"**
+ ```bash
+ # Install LaTeX distribution
+ # See installation steps above
+ ```
+
+2. **Missing LaTeX packages**
+ ```bash
+ # Install additional packages
+ sudo apt-get install texlive-lang-indonesian
+ sudo apt-get install texlive-fonts-extra
+ ```
+
+3. **Font issues**
+ ```bash
+ # Install Libertine font
+ sudo apt-get install texlive-fonts-extra
+ ```
+
+4. **Image not found**
+ - Ensure images are in `manuscript/images/`
+ - Check image file names match LaTeX references
+
+5. **Bibliography issues**
+ ```bash
+ # Use biber instead of bibtex
+ biber book
+ ```
+
+6. **Permission denied**
+ ```bash
+ # Fix file permissions
+ chmod +x build-latex.sh start-preview.sh
+ ```
+
+### Build Errors
+
+1. **Check LaTeX log files:**
+ ```bash
+ # Look for errors in output/book.log
+ cat output/book.log | grep -i error
+ ```
+
+2. **Clean and rebuild:**
+ ```bash
+ make clean
+ make all
+ ```
+
+3. **Check file paths:**
+ - Ensure all `\input{}` files exist
+ - Check image paths are correct
+
+### Web Server Issues
+
+1. **Port already in use:**
+ ```bash
+ # Change port in server.py
+ port = 8001 # or any available port
+ ```
+
+2. **Python not found:**
+ ```bash
+ # Use python3 instead
+ python3 server.py
+ ```

+```
+
+#### **Step 2: Open Browser**
+- Go to `http://localhost:8000`
+- The browser should open automatically
+
+#### **Step 3: Explore**
+- View the complete book structure
+- See all chapters and sections
+- Try build options (with helpful guidance)
+
+## ๐ **What You'll See**
+
+### **Main Interface Features:**
+- ๐ **Book Title & Description**
+- ๐ **Build Options** (4 different types)

+ - macOS: `brew install --cask mactex`
+ - Linux: `sudo apt-get install texlive-full`
+
+2. **Option B:** Use Docker (when network issues are resolved)
+ - `docker-compose up latex-simple`
+
+## ๐ **Success Metrics**
+
+- โ
**Zero Dependencies** - Works with just Python
+- โ
**Cross-Platform** - Windows, macOS, Linux
+- โ
**User-Friendly** - Clear interface and guidance
+- โ
**Professional** - Beautiful, responsive design
+- โ
**Functional** - Complete preview system
+- โ
**Extensible** - Ready for LaTeX integration
+
+## ๐ **Support**
+
+If you encounter any issues:
+
+1. **Check Python installation:** `python --version`
+2. **Test the system:** `python test-build.py`
+3. **Check port availability:** Try a different port in `preview-server.py`
+4. **Review logs:** Server output shows detailed information
+
+---
+
+๐ **Your LaTeX preview system is ready and working!**
+
+The interface is beautiful, functional, and provides a complete preview of your C++ Qt Learning Book. PDF generation will work once LaTeX is installed, but the preview system itself is fully operational.
