The document provides instructions for an assignment to redesign a hello-world board by adding a button and LED with current-limiting resistor. It describes designing the schematic in Eagle, exporting a board image file, and milling and soldering the board. Key components include an Attiny 44 microcontroller, resonator, header, resistor, capacitor, and FTDI board with the added button and LED.
