🎯 Usage

Three Ways to Build

#### 1. Shell Script (Most Flexible)

./build-book.sh          # All formats
./build-book.sh html     # HTML only
./build-book.sh pdf      # PDF only
./build-book.sh epub     # EPUB only
./build-book.sh clean    # Clean artifacts

#### 2. Make (Simplest)

make                     # All formats
make html                # HTML only
make pdf                 # PDF only
make epub                # EPUB only
make view                # Build HTML and open
make clean               # Clean artifacts

#### 3. npm (Node Developers)

npm run build            # All formats
npm run build:html       # HTML only
npm run build:pdf        # PDF only
npm run build:epub       # EPUB only
npm run view:html        # Open HTML
npm run clean            # Clean artifacts

🎨 Customization

Using Your Cover Images

The build script automatically detects:

larc-book.png (preferred) - Your main cover

cover.png (fallback) - Alternative name

For EPUB, it will use whichever it finds first.

Diagram Conversion

Mermaid diagrams in /diagrams/ are automatically converted to PNG images:

Width: 1200px
Background: Transparent
Output: build/output/images/*.png

Styling

Edit the CSS in build-book.sh around line 120 to customize:

Colors (primary: #667eea, secondary: #764ba2)
Typography
Code block styling
Responsive breakpoints

🐛 Troubleshooting

"Command not found: pandoc"

brew install pandoc

"Command not found: pdflatex"

brew install --cask mactex-no-gui
export PATH="/Library/TeX/texbin:$PATH"

Diagrams not converting

npm install -g @mermaid-js/mermaid-cli

Cover image not appearing in EPUB

Ensure you have either:

larc-book.png in the book directory, OR
cover.png in the book directory

PDF errors with LaTeX

Try using Prince XML instead:

Download from https://www.princexml.com/
Script auto-detects and uses it if available

🎉 Success!
