-# Running it manually
+## Constraints
+The idea with constraints is basically to have some logic formula that constraints the items and their rates along an edge.
+So for example if an inserter has a filter configured, its constraints will only allow the specific items as configured by the filter.
+Another example is an assembly machine, which will impose constraints on anything going into it, to only be the items that it needs for the recipe.
 
+Constraints can then be propogated and combined upstream, so that an inserter going into an assembly machine also only selects the items that can actually go into that machine.
+For propogation, the constraints will be combined by either an intersection or a union.
+For example an inserter will perform an intersection, because it can only accept things that fit its specific configuration and any downstream configuration.
+But a belt will perform a union, because might have constraints coming from inserters taking from them and downstream belts so the items can take either path.
+Basically the constraints for every edge will be combined using an intersection with the constraints of the node itself, and then all downstream edge constraints will be combined using a union to form the final upstream constraint.
