 Library initialization
 ----------------------
 
+You first need to create an ICSC object using one of the constructors:
+
 ```C++
-ICSC.begin(stationId, baudRate);
-ICSC.begin(stationId, baudRate, &SerialPort);
-ICSC.begin(stationId, baudRate, &SerialPort, DEPin);
-ICSC.begin(stationId, baudRate, DEPin);
+ICSC(Stream *d, uint8_t station);
+ICSC(Stream &d, uint8_t station);
+ICSC(Stream *d, uint8_t station, int depin);
+ICSC(Stream &d, uint8_t station, int depin);
 ```
 
-Initialize the serial port and internal structures. stationId is the ID of the local station. Set the baud rate to be the same on all stations. &SerialPort is a pointer to a HardwareSerial device, such as &Serial1. If not specified, defaults to &Serial. DEPin is the pin to use to control the RE#/DE pins of an RS-485 transceiver chip if needed. If not specified RE#/DE operation is disabled.
+The `Stream` is the device you wish to communicate over. `station` is the number (or single letter code) of this station, and `depin` is, if provided, the DE/RE pin pair of a MAX485 chip or similar.
 
 Example:
 
 ```C++
 #include <ICSC.h>
 
+ICSC icsc(Serial, 'A', 3);
+
 void setup()
 {
-  ICSC.begin(3, 115200, &Serial1);
+  icsc.begin();
 }
 ```
 
 Register a reception command
 ----------------------------
 
 ```C++
-ICSC.registerCommand(commandID, commandCallback);
+ICSC::registerCommand(commandID, commandCallback);
 ```
 
 Register a new command to be acted upon. Calls the function commandCallback when a packet with this commandID is received.
 
 Example:
 
 ```C++
-ICSC.registerCommand('T', &tick);
+icsc.registerCommand('T', &tick);
 
 void tick(unsigned char source, char command, unsigned char length, char *data)
 {
@@ -55,52 +59,52 @@ Unregister a reception command
 ------------------------------
 
 ```C++
-ICSC.unregisterCommand(commandID);
+ICSC::unregisterCommand(commandID);
 ```
 
 Remove a registered callback command from the list of recognized commands at this station.
 
 Example:
 
 ```C++
-ICSC.unregisterCommand('T');
+icsc.unregisterCommand('T');
 ```
 
 Send a packet
 -------------
 
 ```C++
-ICSC.send(destination, commandID, length, data);
+ICSC::send(destination, commandID, length, data);
 ```
 
 Send a packet to a remote station. The commandID should match a command registered in the remote station. Length is the number of bytes of data to include in the packet. Data is a pointer to the data to send (should be cast to a char * if it isn't already).
 
 Example:
 
 ```C++
-ICSC.send(6, 'T', 5, (char *)&myData);
+icsc.send(6, 'T', 5, (char *)&myData);
 ```
 
 Send a broadcast
 ----------------
 
 ```C++
-ICSC.broadcast(command, length, data);
+ICSC::broadcast(command, length, data);
 ```
 
 Send a packet to all stations. The default address for broadcasting is 0 (can be edited in the ICSC.h file). Apart from that broadcast() works like send().
 
 Example:
 
 ```C++
-ICSC.broadcast('T', 1, (char *)&myData);
+icsc.broadcast('T', 1, (char *)&myData);
 ```
 
 Performing reception
 --------------------
 
 ```C++
-ICSC.process();
+ICSC::process();
 ```
 
 This function should be called during any long loops, and on every pass of the main loop() function.
