Worked on the oracle-japan/ocitutorials repository to update and refine the Compute Instance Tutorial, ensuring alignment with the latest Oracle Cloud Infrastructure UI and Oracle Linux 8. Focused on technical writing and documentation using Markdown, the work involved revising image references, updating operating system details, and clarifying networking and SSH key generation steps. Multiple commits addressed formatting, typo corrections, and improved overall readability, enhancing the onboarding experience for new users. The approach emphasized accuracy, maintainability, and clear commit history, resulting in documentation that reduces user confusion and supports repository standards for quality and traceability in technical content.
