This document discusses the Empanada project, which aims to create a simple and hackable dashboard software using a Raspberry Pi. The project involves setting up a Raspberry Pi, connecting devices to it, and developing software to power an informative workspace. The software will retrieve news and metrics through web APIs and events, and display information on devices connected to the Raspberry Pi. It will also allow bidirectional communication by sending and receiving signals through the Raspberry Pi's input/output pins.
