Worked on enhancing the documentation for the DAG command in the iterative/dvc.org repository, specifically detailing the new --collapse-substages flag. This update clarified how the flag merges foreach and matrix stages into a single node while preserving graph edges, making the command’s behavior more transparent for users. The work focused on improving user onboarding and discoverability by providing concise, technically accurate explanations. Collaborated with another contributor to ensure documentation standards were met, utilizing Markdown and technical writing skills. No major bugs were addressed during this period, with efforts concentrated on delivering clear, maintainable documentation to support developer experience and API understanding.
