Worked on the docker/docs repository to update the Debian installation guide, ensuring documentation accurately reflected the transition to Debian Testing and the new stable codename 'trixie'. Focused on technical writing and documentation using Markdown, the update clarified the mapping from 'bookworm' to 'trixie' and documented the current status of Debian codenames to reduce ambiguity for users. No bugs were addressed during this period, as the primary goal was to improve clarity and maintain alignment with evolving Debian distributions. The work emphasized maintenance and traceability, with all changes committed for review, supporting users installing Docker on Debian-based systems.
