This document summarizes a study on developers' motivation to document code. Through interviews and surveys, researchers identified hindering and motivating factors for code documentation. Hindering factors included documentation being tedious, difficult, time-consuming, and interrupting coding work. Motivating factors included documentation improving code comprehensibility, order, and quality. The researchers propose designing a solution to encourage documentation by emphasizing motivating factors and mitigating hindering ones. They plan to further validate findings through a quantitative questionnaire. The goal is to increase developers' internal motivation to document code.
