Nathan Ostgard updated the Unity SDK installation and upgrade guidance in the embrace-io/embrace-docs repository, focusing on improving onboarding and reducing configuration errors for developers. He removed the automated scoped registry from the installation flow and introduced clear manual removal steps, enhancing the documentation’s clarity and maintainability. By adding visuals that illustrate scoped registry steps and package manager settings, Nathan leveraged his skills in technical writing and documentation using Markdown. The work addressed common pain points in Unity SDK workflows, streamlining the upgrade process and making it easier for developers to follow best practices, though the scope was limited to documentation updates.
