+## We need your support
+This CiviCRM extension is provided as Free and Open Source Software, 
+and we are happy if you find it useful. However, we have put a lot of work into it 
+(and continue to do so), much of it unpaid for. So if you benefit from our software, 
+please consider making a financial contribution so we can continue to maintain and develop it further.
+
+If you are willing to support us in developing this CiviCRM extension, 
+please send an email to info@systopia.de to get an invoice or agree a different payment method. 
+Thank you!
