Worked on improving documentation for the leancodepl/patrol repository, focusing on enhancing the accuracy and consistency of promotional graphic references across all README files. Addressed a bug by correcting the path to the promotional graphic and updating banners to reference a new image, which helped ensure clear and consistent branding throughout the documentation. Utilized Markdown for content updates and leveraged version control practices to manage and track changes efficiently. The work emphasized precise, small-scale improvements that reduced confusion for contributors and users, demonstrating skills in content management, documentation maintenance, and Git-based workflows to support repository clarity and usability.
