+Linux Userspace GPIO Library
+============================
+
+ * Export and Unexport GPIO pins
+ * Interrupt support (*)
+ * Rewrite of NoccyLabs RaspIO 
+ 
+
+## Interrupts
+
+For interrupts to work, you need to first bind the interrupt handler, and then
+make sure to call on `Gpio#refresh()` every cycle to poll the interrupt flag on
+the selected pins.
+
+    $gpio = new Gpio();
+
+    $gpio->onInterrupt(Gpio::get(0), "rising", function($e) { ... });
+    
+    while (..) {
+        ..
+        $gpio->refresh();
+    }
