+The Computer Audio adapter is a cross-over adapter that connects the microphone pin of a computer's TRRS audio port to the speaker output of the HamShield, and vice versa. All you have to do to use it is assemble it and plug it in.
+
+# Assembly
+
+Assembly of the adapter requires access to a soldering iron. Populate the components as follows:
+
+R1 = 1.2 kOhms (brown, red, red, gold)
+R2 = 10 kOhms (brown, black, orange, gold)
+R3 = 1.2 kOhms (brown, red, red, gold)
+
+C1 = 0.01 uFarads
+C2 = 0.01 uFarads
+
+JP1 = four pin male header
+J1 = TRRS jack
+
+You will also need to solder a four pin female header to JP3 on the HamShield (just to the side of the HamShield's audio jack).
+
+When you plug the audio adapter in to the HamShield, the TRRS jack of the adapter should line up with the TRRS jack of the shield.
