+\subsection{Connecting to Programmer}
+These notes may be redundant, need to double check.
+
+When connecting, have a base setup that works as a sanity check.
+
+It may be possible to blow out atmega328p pins if you leave attiny running, thne
+plug in the cable back to front (i.e. pin 13 in 9).
+
+You might need to reboot the arduino completely. 
+
+From Programmer Source code:
+- Upload to arduino and power off
+    - Connect ATtiny10 as shown
+    - Power on and open the serial monitor
+    - If things are working so far you should
+      see "NVM enabled" and "ATtiny10/20/40 connected".
+    - Input one-letter commands via serial monitor:
+
+This programmer is not foolproof, so establish a routine, and keep a working
+model (pcb w/attiny) as a prototype to isolate what is broken.
