Greg contributed to the pantheon-systems/documentation repository by enhancing the clarity and usability of Drupal LTS documentation. He developed a feature that clearly distinguishes between Drupal 7 core LTS and contrib LTS, addressing a common source of user confusion. Using Markdown and his documentation skills, Greg also improved the compatibility chart by removing non-breaking spaces, which corrected the alignment of checkmarks and ensured accurate presentation of supported Drupal versions. His work focused on refining the supported-drupal.md file, resulting in more accessible and reliable documentation for teams onboarding with Drupal. The scope was targeted, with depth in documentation structure and presentation.
