 # ShiftRegister 74HC595 Arduino Library
-This library simplifies shift registers usage. It allows, for instance, to set shift register pins just like normal Arduino pins: `sr.set(1, HIGH)`.
 
-The **documentation** is available at http://shiftregister.simsso.de/.
+This library simplifies the usage of shift registers. For instance, it allows to set pins of the shift register just like normal Arduino pins:
