+# Usage: go-modules-targeted-update.sh
+#
+# Batch update specific dependencies for sidecars.
+#
+# Required environment variables
+# CSI_RELEASE_TOKEN: Github token needed for generating release notes
+# GITHUB_USER: Github username to create PRs with
+#
+# Instructions:
+# 1. Login with "gh auth login"
+# 2. Copy this script to the Github org directory (one directory above the
+# repos)
+# 3. Change $modules, $releases and $org if needed.
+# 4. Set environment variables
+# 5. Run script from the Github org directory
+#
+# Caveats:
+# - This script doesn't handle interface incompatibility of updates.
+#   You need to resolve interface incompatibility case by case. The
+#   most frequent case is to update the interface(new parameters,  
+#   name change of the method, etc.)in the sidecar repo and make sure
+#   the build and test pass.
