Worked on the ember-learn/guides-source repository to streamline the upgrade documentation for Ember Octane by removing outdated guides and implementing redirects to the latest edition’s upgrade path. The approach involved updating the table of contents and adjusting test counts to match the new documentation structure, ensuring users are directed to the most current resources. All changes were consolidated into a single commit to maintain clarity and reduce confusion for developers navigating the upgrade process. Utilized Markdown and YAML for content management and technical writing, focusing on documentation accuracy and improved navigation without introducing new bugs during the update period.
