Basic options

You can:

• Load the template in any of the provided languages
• Upload your own background
• Choose the page orientation (landscape or portrait)

Customize the template

The pdfs are generated using pdfmake. You can manipulate the text that will be generated by editing the template - basically anything is possible, as long as the result is valid for pdfmake. I would recommend playing a bit with it, making small incremental changes, until you're happy with the result.
