The new README page in Apollo Studio aims to onboard developers by providing essential instructions and metadata for consuming and contributing to a graph. The page includes helpful information such as the graph's name, endpoint, commit hash, and links to Explorer and changelog. Developers can customize the README content with default markdown templates and include pertinent details like descriptions, access instructions, and example operations. The feature also offers graph shortcodes that allow referencing variables with just a click, making it easier for developers to get started with the graph.
