+# Idea
+- Everything is a graph
+- Each Entity is a node in the graph
+    - What extra information to include
+- Each Edge represents that certain items can move from one node to the other
+    - Specify what items can move over the edge (for example because of filters)
+    - Outgoing and incoming priority
+    - Capacity ?
+    - What extra information to include
+
+# Interactions
+The Construction basically comes down to a large table mapping the different interactions between all the types of entities.
+
+## Belts
+For the purpose of my analysis, you can split a belt into the two sides, as they act independent of one another.
+
+### Belt-Belt
+Direct 1-to-1 connection, is the simplest and most common way two belts are connected.
+In this configuration you have 1 belt basically forwarding everything onto another belt, where each side of the source belt feeds into the corresponding side of the target belt.
+For example if you have a simple line of belts forming a long line, they are all direct 1-to-1 connected.
+
+Sideloading, is a more special case. This happens when the target belt already has another belt connected and now the new source belt is connected from the side (as the name suggests).
+In this configuration both sides of the source belt are going into one side of the target belt. 
+
+### Belt-Splitter
+The splitter can only accept direct 1-to-1 style connections going into it, from belts or the output of underground belts.
+
+The ouput of a splitter basically acts the same way as a normal belt would.
+
+### Belt-UndergroundBelt
+The input side of the underground supports direct 1-to-1 connections, if the other source belt is coming from the same direction (so no turn is being made).
+The input can also be sideloaded, however opposed to normal belt sideloading, only the upstream side of the source belt will feed into the target belt and the other side of the source belt will not be connected.
+
+The output again acts like a normal belt.
+
+### Belt-Direct output machines (miner, recycler, etc.)
