Step 3

Figure out how you're going to wire up your 2x3 header block to the legs. Basically just connect everything together. MISO to MISO, VCC to VCC, etc.

Step 4

Before you solder anything, a note on the legs: Add a couple extra legs for alignment, stress relief and stability. At least fill the first 2 holes on both sides (atmega 1 & 2, 27 & 28).
