+# GitHub Actions Workflow: Brand Name Check for Changes
+# --------------------------------------------------------------------
+# Description:
+# This GitHub Actions workflow checks pull requests (PRs) for deprecated
+# terms related to "Cloudberry" and "Greenplum". It ensures consistent
+# usage of updated branding throughout the project.
+#
+# Purpose:
+# - Identify outdated terms such as "Cloudberry Database" or "Greenplum".
+# - Automatically comment on the PR, suggesting replacements where needed.
+# - Encourage the use of "Apache Cloudberry" or "Cloudberry" as standards.
+#
+# How it works:
+# - Triggers when a PR is opened, edited, or synchronized with its branch.
+# - Scans only the changes (diffs) in the PR, focusing on modified content.
+# - Posts a comment if deprecated terms are detected in the changes.
+#
+# Note: This GitHub Actions is not a required option for merging one
+# Pull Request, just as one reference for the brand check.
