+# This script lists URLs changed by the target PR. You can jump to target page quickly by clicking those.
+# Syntax: get-changed-urls.sh <PR number> [<page top URL>]
+# Example: 
+# $ get-changed-urls.sh 28542
+# http://localhost:1313/ja/docs/concepts/configuration/manage-resources-containers
+# http://localhost:1313/ja/docs/concepts/policy/limit-range

+# http://localhost:1313/ja/docs/setup/best-practices/cluster-large
+#
+# If no <page top URL> is passed, it will assume "http://localhost:1313".
+# It's the default endpoint for "make container-serve" or "make serve".
+# Please look at the README(https://github.com/kubernetes/website#using-this-repository) to serve endpoint.
+# Or you can pass any strings to <page top URL>.
+# You can get URLs for upstream by passing <page top URL> as "https://kubernetes.io".
