The document discusses why documentation in agile processes is often poor or nonexistent, and provides suggestions for improving documentation. It notes that developers may find documentation difficult due to frequent changes, time pressures, being too close to projects, and not seeing its value. However, documentation provides common understanding, empathy between teams, aids future problem-solving, and helps with onboarding. The document recommends keeping documentation simple, writing it late in development, avoiding duplication, and focusing documentation on immediate goals. It suggests baking documentation into agile processes and having everyone contribute.
