+uvx markitdown input.pdf
+
+# Save to file
+uvx markitdown input.pdf -o output.md
+uvx markitdown input.docx > output.md
+
+# From stdin
+cat input.pdf | uvx markitdown
+```
+
+## Supported Formats
+
+- **Documents**: PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx, .xls)
+- **Web/Data**: HTML, CSV, JSON, XML
+- **Media**: Images (EXIF + OCR), Audio (EXIF + transcription)
+- **Other**: ZIP (iterates contents), YouTube URLs, EPub
+
+## Options
+
+```bash
+-o OUTPUT      # Output file
+-x EXTENSION   # Hint file extension (for stdin)
+-m MIME_TYPE   # Hint MIME type
+-c CHARSET     # Hint charset (e.g., UTF-8)
+-d             # Use Azure Document Intelligence
+-e ENDPOINT    # Document Intelligence endpoint
+--use-plugins  # Enable 3rd-party plugins
+--list-plugins # Show installed plugins
+```
+
+## Examples
+
+```bash
+# Convert Word document
+uvx markitdown report.docx -o report.md
+
+# Convert Excel spreadsheet
+uvx markitdown data.xlsx > data.md
+
+# Convert PowerPoint presentation
+uvx markitdown slides.pptx -o slides.md
+
+# Convert with file type hint (for stdin)
+cat document | uvx markitdown -x .pdf > output.md
+
+# Use Azure Document Intelligence for better PDF extraction
+uvx markitdown scan.pdf -d -e "https://your-resource.cognitiveservices.azure.com/"
+```
+
+## Notes
+
+- Output preserves document structure: headings, tables, lists, links
+- First run caches dependencies; subsequent runs are faster
+- For complex PDFs with poor extraction, use `-d` with Azure Document Intelligence
