Worked on the gitlabhq/gitlab-runner repository to update documentation for the log_format configuration, ensuring that users are accurately informed about the supported logging options. Focused on aligning the documentation with the actual capabilities of the runner by clarifying that only 'text', 'json', and 'runner' formats are supported, replacing outdated references to 'info'. Used Markdown to structure the documentation and applied strong attention to detail to improve consistency across sections. The update aimed to reduce user misconfigurations and support queries by providing clear, traceable guidance. All changes were consolidated into a single, reviewable commit, emphasizing documentation and process clarity.
