 Linux Userspace GPIO Library
 ============================
 
- * Export and Unexport GPIO pins
+Current and planned features:
+
+ * Export and Unexport GPIO pins via sysfs
  * Interrupt support (*)
  * Hardware-neutral rewrite of NoccyLabs RaspIO 
  * Compatible with psr/logs LoggerInterface for logging
+ * Bit-banged SPI/I2C/1Wire
+
+
+## Gpio
+
+Without a mapper active, the GPIOs adressed are the direct exported GPIO numbers,
+not necessarily in any logical order. Requesting `$gpio[22]` gives you `GPIO22`.
+
+    $gpio = new Gpio();
+    $gpio1 = $gpio[1];
+
+
+### With a Mapper
+
+With a mapper the pins are arranged logically starting at 0. For example, with
+the WiringPi mapper, `$gpio[0]` would return `GPIO17` and so on. The `GpioPin#getPin()`
+method will still return the actual GPIO (i.e. *17* rather than *0*).
+
+    $gpio = new Gpio();
+    $mapper = new WiringPiMapper(2);
+    $gpio->setMapper($mapper);
+
+    $gpio17 = $gpio[0];
