+  Thanks for creating a Pull Request! Before you submit, please ensure that the following requirements are met:
+  - Current version constraint does not allow using the latest RuboCop release.
+  - The `master` branch of the Jekyll Repository has been updated to use the latest RuboCop release.
+
+  Checklist:
+  - Has updated ONLY the badge in the `README.md`.
+  - Has updated ONLY the RuboCop version in the `rubocop-jekyll.gemspec`.
+  - [OPTIONAL] Has updated the `.rubocop.yml`
+-->
+
+<!--
+  Replace [RUBOCOP-VERSION] below with valid information. e.g. Allowing the use of RuboCop-0.63.0 would be:
+
+    RuboCop v0.63.0 Release Details: https://github.com/rubocop-hq/rubocop/releases/tag/v0.63.0
+
+  If there is an intermediate RuboCop version, refer to that version as well. e.g. When bumping directly from
+  v0.62.x to v0.63.1:
+
+    RuboCop v0.63.0 Release Details: https://github.com/rubocop-hq/rubocop/releases/tag/v0.63.0
+    RuboCop v0.63.1 Release Details: https://github.com/rubocop-hq/rubocop/releases/tag/v0.63.1
+-->
+
+RuboCop v[RUBOCOP-VERSION] Release Details: https://github.com/rubocop-hq/rubocop/releases/tag/v[RUBOCOP-VERSION]
