Converting to Word Format

Option 1: Using Pandoc (Recommended)

If you have Pandoc installed:

# Install Pandoc (if not already installed)
# macOS: brew install pandoc
# Windows: choco install pandoc
# Linux: sudo apt-get install pandoc

# Convert individual files
pandoc headroom-project-charter.md -o headroom-project-charter.docx
pandoc headroom-architecture.md -o headroom-architecture.docx
pandoc headroom-decision-log.md -o headroom-decision-log.docx
pandoc headroom-executive-summary.md -o headroom-executive-summary.docx

# Or convert all at once
for file in headroom-*.md; do
  pandoc "$file" -o "${file%.md}.docx"
done

Option 2: Using Online Converters

If Pandoc is not available:

1. Visit https://cloudconvert.com/md-to-docx
2. Upload the .md file
3. Download the .docx file

Alternatively:

• https://www.markdowntopdf.com/ (converts to PDF)
• https://dillinger.io/ (online Markdown editor with export)

Option 3: Copy-Paste Method

1. Open the .md file in any Markdown viewer (VSCode, Typora, MacDown)
2. Copy the rendered content
3. Paste into Microsoft Word
4. Format as needed

Mermaid Diagrams

The architecture document contains Mermaid diagrams. To render them:

In Markdown Viewers

• VSCode: Install "Markdown Preview Mermaid Support" extension
• Typora: Built-in Mermaid support
• MacDown: May require plugin

For Word Conversion

Mermaid diagrams don't convert directly to Word. Options:

1. Render to images first:

   # Using mermaid-cli
   npm install -g @mermaid-js/mermaid-cli
   mmdc -i architecture.md -o architecture.docx
   

2. Use online renderer:

   • Visit https://mermaid.live/
   • Paste Mermaid code
   • Export as PNG/SVG
   • Insert into Word document

3. Keep as code blocks:

   • Diagrams will appear as text in Word
   • Acceptable for technical documentation

Recommended Reading Order

For Project Owner (You)

1. Start with headroom-executive-summary.md (overview)
2. Read headroom-decision-log.md (verify all decisions captured)
3. Review headroom-project-charter.md (detailed requirements)
4. Study headroom-architecture.md (technical deep-dive)

For Associate

1. headroom-executive-summary.md (context)
2. headroom-architecture.md (technical implementation)
3. headroom-project-charter.md (detailed requirements as needed)
