How to contribute to this Wiki

You can simply add text by using the Edit command ( password = pw4zw!ki ). See for instruction below. For security reasons, it is not possible to upload pictures and treatments directly. If you want to include pictures and provide sample treatment, there are two way to proceed:

  • You send the material to Schmid Stefan <>, he will upload it, and you can refer to it.
  • You make an external reference to a URL at your location, and you inform me about it. I will upload it to the z-Tree-Wiki and change the reference. Please to only link images and treatments that can be uploaded to this Wiki. This way, it is much easier to keep the Wiki in shape.
