+### Example: Generating a PDF from HTML template
+
+See our example HTML template in [`Doc/example.html`](https://github.com/shuhanmirza/SpringBooTex/blob/main/Doc/example.html)
+You can see that, the thymeleaf templating has been used in the template.

+And the generated PDF is  
+![example-html.pdf](Doc/example-html.png)
+
+At first, SpringBooTex prepares the html using Thymeleaf template engine. Then it leverages `openhtmltopdf` to render PDF from html. If you do not want to provide fonts through HTML, you can provide it by adding font urls in the `fileUrlMap`. SpringBootex will download and add the fonts during PDF rendering.
