The preparation and completion of this project required a substantial amount of time and costs. Still it was my clear decision to offer this project for free and accessible for everyone.
To be able to offer future projects like this, it would of course be incredible generous to receive a small amount to cover the costs. But I want to emphasize that this is completely voluntary and without any reservations.

Much appreciated, thank you!
