During June 2025, Zach Lysobey contributed to the pact-foundation/pact-js repository by addressing a documentation bug that impacted developer onboarding. He updated the installation instructions in the README, replacing the deprecated npm i -S command with the current npm install --save-dev syntax. This change, implemented using Markdown and documentation best practices, clarified dependency management for new users and reduced confusion during setup. Zach maintained a clear and traceable commit history, ensuring future updates would be straightforward. While the work focused on a single documentation fix, it demonstrated attention to detail and an understanding of evolving npm workflows and developer experience.
