Code Review

This pull request adds a verification step to the installation instructions, which is a great improvement for user experience. However, I've identified a formatting issue in the markdown that would cause rendering problems, and the provided verification command is incorrect and would result in an error. My review includes a single, comprehensive suggestion to fix both the markdown structure and the command, recommending the use of the more standard docling --version.

[gemini-code-assist]

There's a formatting issue here that causes the explanatory text to be rendered as part of a code block. Additionally, the proposed command to verify the installation is incorrect and will raise an AttributeError because docling.__version__ is not defined.

A better approach is to use the docling --version command, which is the standard way to check the version of a CLI tool. This is both simpler for the user and correctly fetches the version information.

Here is a suggestion that fixes both the formatting and the command:

Suggested change

	pip install docling
	To verify that Docling was installed successfully, you can check the version:
	```bash
	python -c "import docling; print(docling.__version__)"
	```
	```
	pip install docling

To verify that Docling was installed successfully, you can check the version:

docling --version
