Running the Program

Run the CLI application:

cargo run

The program will prompt you for a Markdown file path.

Example:

Enter the markdown file path:
example.md

If the file is valid, the program will:

1. Read the Markdown file
2. Convert it to HTML
3. Generate an output HTML file

---

Example Markdown Input

# Hello Rust

This is **Markdown** converted to HTML.

- Item 1
- Item 2
- Item 3

---

Example HTML Output

<h1>Hello Rust</h1>
<p>This is <strong>Markdown</strong> converted to HTML.</p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
