 ## `input_bus : Netlist_ast.ident -> unit`
-Updates the context such that the provided identifier is mapped to the bits given by the user, bit by bit, in `stdin` (it asks the value of every wire).
+Updates the context such that the provided identifier is mapped to the bits given by the user, according to the mode given in the CLI, in `stdin`.
+Description of the modes:
+- 'b'(it) : legacy mode. Here only because I didn't dare to remove it. It asks for the value of the bus wire per wire, bit per bit. Also officially known as "masochist mode".
+- 'l'(ittle) : default mode. Asks for the input in the form of a `n` bit word. Is read as little-endian.
+- 'B'(ig) : Asks for the input in the form of a `n` bit word. Is read a big-endian.
+- 'i'(nteger) : Asks for the input in the form of an integer. Its binary representation is converted in a little-endian mode.
 
 ## `input : Netlist_ast.program -> unit`
 Calls [input_wire](#input_wire-netlist_astident-unit) or [input_bus](#input_bus-netlist_astident-unit) on every identifier marked as an input in the program.
