 # Markdown Tools
 
-## Overview
+Convert documents to markdown with image extraction and Windows/WSL path handling.
-
-This skill provides document conversion to markdown with Windows/WSL path handling support. It helps convert various document formats to markdown and handles path conversions between Windows and WSL environments.
-
-## Core Capabilities
-
-### 1. Markdown Conversion
-Convert documents to markdown format with automatic Windows/WSL path handling.
-
-### 2. Confluence Export Processing
-Handle Confluence .doc exports with special characters for knowledge base integration.
 
 ## Quick Start
 
-### Convert Any Document to Markdown
+### Install markitdown with PDF Support
 
 ```bash
-# Basic conversion
+# IMPORTANT: Use [pdf] extra for PDF support
-markitdown "path/to/document.pdf" > output.md
+uv tool install "markitdown[pdf]"
 
-# WSL path example
+# Or via pip
-markitdown "/mnt/c/Users/username/Documents/file.docx" > output.md
+pip install "markitdown[pdf]"
 ```
 
-See `references/conversion-examples.md` for detailed examples of various conversion scenarios.
+### Basic Conversion
-
-### Convert Confluence Export
 
 ```bash
-# Direct conversion for simple exports
+markitdown "document.pdf" -o output.md
-markitdown "confluence-export.doc" > output.md
+# Or redirect: markitdown "document.pdf" > output.md
-
-# For exports with special characters, see references/
 ```
 
-## Path Conversion
+## PDF Conversion with Images
 
-### Windows to WSL Path Format
+markitdown extracts text only. For PDFs with images, use this workflow:
 
-Windows paths must be converted to WSL format before use in bash commands.
+### Step 1: Convert Text
-
-**Conversion rules:**
-- Replace `C:\` with `/mnt/c/`
-- Replace `\` with `/`
-- Preserve spaces and special characters
-- Use quotes for paths with spaces
-
-**Example conversions:**
-```bash
-# Windows path
-C:\Users\username\Documents\file.doc
-
-# WSL path
-/mnt/c/Users/username/Documents/file.doc
-```
-
-**Helper script:** Use `scripts/convert_path.py` to automate conversion:
 
 ```bash
-python scripts/convert_path.py "C:\Users\username\Downloads\document.doc"
+markitdown "document.pdf" -o output.md
 ```
 
-See `references/conversion-examples.md` for detailed path conversion examples.
+### Step 2: Extract Images
 
-## Document Conversion Workflows
-
-### Workflow 1: Simple Markdown Conversion
-
-For straightforward document conversions (PDF, .docx without special characters):
-
-1. Convert Windows path to WSL format (if needed)
-2. Run markitdown
-3. Redirect output to .md file
-
-See `references/conversion-examples.md` for detailed examples.
-
-### Workflow 2: Confluence Export with Special Characters
-
-For Confluence .doc exports that contain special characters or complex formatting:
-
-1. Save .doc file to accessible location
-2. Use appropriate conversion method (see references)
-3. Verify output formatting
-
-See `references/conversion-examples.md` for step-by-step command examples.
-
-## Error Handling
-
-### Common Issues and Solutions
-
-**markitdown not found:**
 ```bash
-# Install markitdown via pip
+# Create assets directory alongside the markdown
-pip install markitdown
+mkdir -p assets
 
-# Or via uv tools
+# Extract images using PyMuPDF
-uv tool install markitdown
+uv run --with pymupdf python scripts/extract_pdf_images.py "document.pdf" ./assets
 ```
 
-**Path not found:**
+### Step 3: Add Image References
+
+Insert image references in the markdown where needed:
+
+```markdown
+![Description](assets/img_page1_1.png)
+```
+
+### Step 4: Format Cleanup
+
+markitdown output often needs manual fixes:
+- Add proper heading levels (`#`, `##`, `###`)
+- Reconstruct tables in markdown format
+- Fix broken line breaks
+- Restore indentation structure
+
+## Path Conversion (Windows/WSL)
+
 ```bash
-# Verify path exists
+# Windows → WSL conversion
-ls -la "/mnt/c/Users/username/Documents/file.doc"
+C:\Users\name\file.pdf → /mnt/c/Users/name/file.pdf
 
-# Use convert_path.py helper
+# Use helper script
-python scripts/convert_path.py "C:\Users\username\Documents\file.doc"
+python scripts/convert_path.py "C:\Users\name\Documents\file.pdf"
 ```
 
-**Encoding issues:**
+## Common Issues
-- Ensure files are UTF-8 encoded
+
-- Check for special characters in filenames
+**"dependencies needed to read .pdf files"**
-- Use quotes around paths with spaces
+```bash
+# Install with PDF support
+uv tool install "markitdown[pdf]" --force
+```
+
+**FontBBox warnings during PDF conversion**
+- These are harmless font parsing warnings, output is still correct
+
+**Images missing from output**
+- Use `scripts/extract_pdf_images.py` to extract images separately

-Python script to automate Windows to WSL path conversion. Handles:
-- Drive letter conversion (C:\ → /mnt/c/)
-- Backslash to forward slash
-- Special characters and spaces
-
-## Best Practices
-
-1. **Convert Windows paths to WSL format** before bash operations
-2. **Verify paths exist** before operations using ls or test commands
-3. **Check output quality** after conversion
-4. **Use markitdown directly** for simple conversions
-5. **Test incrementally** - Verify each conversion step before proceeding
-6. **Preserve directory structure** when doing batch conversions
