 To get started quickly, you can take a look at my example project [here](Examples/SwiftSerialExample). In order to run the example properly, you need to connect one of your (USB/UART) serial ports in a loopback manner. Basically, you short the TX and RX pins of the serial port.
 
 ```bash
-git clone https://github.com/yeokm1/SwiftLinuxSerial.git
+git clone https://github.com/yeokm1/SwiftSerial.git
-cd SwiftLinuxSerial/Examples/SwiftSerialExample/
+cd SwiftSerial/Examples/SwiftSerialExample/
 swift build

+#For Linux: You need root to access the serial port. Replace /dev/ttyUSB0 with the name of your serial port under test
 sudo ./.build/debug/SwiftSerialExample /dev/ttyUSB0
 
+#For Mac: Root is not required
+./.build/debug/SwiftSerialExample /dev/tty.usbserial

 #If all goes well you should see a series of messages informing you that data transmitted has been received properly.
