Gianluca Corsini enhanced the gazebosim/docs repository by updating the Ubuntu installation prerequisites documentation to include the curl utility, addressing a common onboarding hurdle for Gazebo Jetty users. Focusing on Markdown-based documentation, Gianluca refined install_ubuntu.md to ensure users have all necessary tools before installation, thereby reducing support requests and installation failures. The work centered on improving documentation clarity and traceability rather than code or bug fixes, demonstrating attention to user experience and process reliability. While the scope was limited to a single feature, the update contributed to smoother onboarding and more predictable installation outcomes for the Gazebo Jetty platform.
