 Now that the image has been turned into an installer, you may put the microSD card into the Beagle Bone (without power).
-If there is a fourth pin, usually red, do not use.  We only need input, output, and ground.
+On a typical serial to USB adapter, and almost all others, the colors are white (receive), green (transmit), black (ground), red (5V power).  Do not use the red cable unless you know what you are doing.  Otherwise, make sure that the adapter's transmit goes to the Beagle's receive, and the adapter's receive to the Beagle's transmit.  The diagram below shows the Beagle's perspective. From left to right, there are 6 pins, so it would be : nothing, white, green, nothing, nothing, black.  The adapter commonly has a name like ttyUSB0, therefore this command should do the trick:
-  sudo screen <devicename> 115200
+  sudo screen /dev/ttyUSB0 115200
-  sudo screen /dev/ttyUSB0 115200 [Example]

-When working with serial connections such as the Beagle Bone Black, and otherwise, screen can be helpful.  You can leverage screen with ssh to tunnel to another host, and then pass a screen command to keep the commands you initiate persistent on the client you connected to.
+Once the Beagle Bone is set up, one can leverage the screen command with ssh to tunnel to another host, and then pass a screen command to keep the commands you initiate persistent on the client you connected to.  That syntax looks like this:
-  ssh -p ### -t user@host.com screen -DRO
+  ssh -p 222 -t user@host.com screen -DRO
-Using screen with usb to serial adapter
-  sudo screen /dev/ttyUSB0 115200
-Some other common speeds are 9600, 57600, 38400, 19200
+Some other common speeds are 9600, 57600, 38400, 19200.  For the Beagle Bone black, I always use 115200.  These speeds are in baud.
