If you want to have a quick overview about the project, please have a look at either of the following PDFs:

PDF describing OpenPetra in general
PDF with Technical Details for Developers

These PDFs explain what OpenPetra does, at what current state of development it is, and how you can help the project and at the same time benefit from the project. They show you attributes that make OpenPetra special.

Please forward these flyers to friends or colleagues or your favourite charity to tell them about OpenPetra!
