+## PDF
+
+With PDF shortcode, you can embed a PDF file in your content.
+
+```
+{{</* pdf "https://example.com/sample.pdf" */>}}
+```
+
+You can also place the PDF file in your project directory and use the relative path.
+
+```
+{{</* pdf "path/to/file.pdf" */>}}
+```
+
+Example:
+
+{{< pdf "https://upload.wikimedia.org/wikipedia/commons/1/13/Example.pdf" >}}
