To add an industry element simply click the burger menu icon and then select the industry you want to add.
You can create connections between elements by clicking one element and than the other element you want to connect.
The rules for creating connections are the same as within DU. (containers can be connected to any element except other containers while other industry elements can only be connected to containers)
Also the normal connection restrictions are in place (10 incoming and 1 outgoing connection, with the exception being containers which have 10 connections for incoming and outgoing each)
The Save / Load and Import / Export features will also come in a later version
At the moment there is no information if resources are missing during the planning. This is being worked on.
There will be more information about the planned industry setup in the near future
There might be a function to add industry based on a recipe. (eg: pure iron will spawn a refiner)
