+
+The {doctitle} is the core of the Refined Storage network.
+You need to connect all the Refined Storage devices to this block.
+
+== Connecting devices
+
+You are supposed to connect every device that depends on the storage network connection to the {doctitle}.
+
+You can connect devices with xref:cable.adoc[cables].
+
+xref:cable.adoc[Cables] are not always necessary, as long as the devices are next to each other in any direction a connection will be established as well.
+
+== Energy
+
+The {doctitle} accepts and consumes Forge Energy (FE).
+Most mods have a way to generate energy, therefore Refined Storage doesn't come by itself with a way to generate energy.
+
+- The energy is extracted per tick.
+- The amount of energy that is extracted depends on the amount of devices, and which devices.
+- Every device type consumes another amount of energy.
+- You can see how many energy each device consumes by right clicking the {doctitle}.
+
+If the {doctitle} runs out of energy, the network will be turned off until there is sufficient energy provided again.
+
+When the {doctitle} is broken, it will maintain its energy.
+
+== Limits
+
+Each Refined Storage network can only have a single {doctitle}.
+It doesn't make sense to connect multiple controllers on the same network.
+
+If you connect another {doctitle} to an already existing network, the {doctitle} will break as an item in the world.
