Julien Cohen-Adad enhanced the neuropoly/neuro.polymtl.ca repository by delivering a new documentation asset, focusing on improving the clarity and visual appeal of project materials. He added the 20250125_NeuroPoly_Bowling.jpg image to the .gitbook/assets directory, supporting better onboarding and external communication without altering the codebase. The work involved careful asset management using Git and GitBook, ensuring repository stability by limiting changes to a single, well-documented commit. While the scope was narrow, the update addressed the need for richer documentation visuals, leveraging skills in version control and documentation tooling to maintain project quality and facilitate easier understanding for new contributors.
