+#### How to configure the server to do post-processing
+There is currently no user interface to configure the post-processing for the server. It has to be added manually to the server config.
+I suggest to start the app and configure the post-processing steps in the settings. Afterwards you close the app and copy the
+post-processing section from the settings.json to your server.json file. To find out, where these files are on your system, read
+[Configuration File](ConfigurationFile.md).
+
+The part you have to copy is
+```
+  postProcessors: [
+    ...
+  ],
+```
