 MarkItDown has optional dependencies for activating various file formats. Earlier in this document, we installed all optional dependencies with the `[all]` option. However, you can also install them individually for more control. For example:
 
 ```bash
-pip install markitdown[pdf, docx, pptx]
+pip install 'markitdown[pdf, docx, pptx]'
 ```
 
 will install only the dependencies for PDF, DOCX, and PPTX files.
