Worked on enhancing the Elevation Profile Synchronize Layers to Project feature within the qgis/QGIS-Documentation repository, focusing on delivering comprehensive and accurate user guidance. Used reStructuredText and technical writing skills to update the user manual, aligning documentation with the actual UI behavior and the map canvas layer structure. The work included expanding content, fixing typos, and collaborating with co-authors to ensure clarity and correctness. These documentation improvements clarified the default state and synchronization behavior, helping users understand how changes in the Layers panel affect the elevation profile. The updates aimed to streamline onboarding and reduce potential support queries for users.
