Which template files are used to compose a certificate?

Hi guys,

I realized that the files in ‘/edx/tutor/data/openedx/staticfiles/templates/certificates’ do not seem to be used to compose a certificate. If have put some remarks in there but they do not show up.

So my questions are:

  1. which template files are being used as default?
  2. how can I make open edx make use these files?

Thanks
Falk
