Worked on the PX4/PX4-user_guide repository to standardize and reorganize test documentation, focusing on improving the structure and clarity of test cards. The approach involved restructuring Markdown files to consistently separate test objectives, preflight checks, flight tests, and expected results, making procedures easier to follow and maintain. Leveraging skills in documentation and technical writing, the changes enhanced the readability and expandability of test procedures, supporting faster onboarding for new contributors. This work improved the maintainability and transparency of the testing workflow, enabling more efficient validation of documentation updates and aligning the repository with established documentation standards for ongoing development.
