+
+INSTRUCTIONS:
+
+For each PR, add a changelog entry that describes what your PR does. Add it to the heading
+for the appropriate package it modifies and include it in this format:
+- [Description] ([Link to PR])
+
+If your PR affects multiple packages, list it multiple times under headings for each package.
+If it affects more general things such as dependency updates or non-package-specific changes,
+add it under a "Dev / docs / playground" section.
+
+You should also update the heading of the latest (upcoming) version if your PR change merits
+it according to semantic versioning. For example, if your PR adds a breaking change, then you
+should change the heading of the (upcoming) version to include a major version bump.
