In the Helfa project we try to adopt as much of the OpenSource or Open Access principle as possible. So the software that is used should be OpenSource. Why? The idea is that we work together transparently. But that also means that our tools should be free - and transparent.
So programs are used like:
    - LibreOffice
    - Drupal
    - Linux
    - Telegram
    - Signal
    - etc.

The OpenSource principle, or the Open Access principle does not only end with the programs, but also goes into our way of working. Meetings are recorded and the minutes are put online so that others can see what has been decided. Of course, not everything has to be put on the web, but the important information should be read by everyone - even if it is only for the sake of transparency.
Other data that belong on the web are documents about concepts, ideas, scientific papers, seminars, etc. The more knowledge is shared, the better it will be for everyone - because knowledge must not die! Knowledge must reach as far as it can. That is why we support OpenSource and Open Access.
