During August 2025, Sonja Leckelt focused on improving the SVWS-NRW/SVWS-Dokumentation repository by addressing German spelling and localization issues in the documentation. She worked primarily with Markdown, using Git for version control to deliver four targeted commits that updated index.md and webclient/anleitungen_zeugnisse/index.md. Her efforts enhanced the clarity and consistency of the documentation, aligning terminology with the user interface and reducing ambiguity for German-speaking users. By refining the documentation’s language and structure, Sonja contributed to a smoother onboarding experience and helped decrease potential support requests, demonstrating skills in documentation quality assurance and German localization within technical writing.
