 ## Release Process
 1. Identify all issues and ongoing PRs that should go into the release, and
   drive them to resolution.
+1. Update dependencies for sidecars via
+   [go-modules-update.sh](https://github.com/kubernetes-csi/csi-driver-host-path/blob/HEAD/release-tools/go-modules-update.sh),
+  and get PRs approved and merged.
 1. Check that all [canary CI
   jobs](https://testgrid.k8s.io/sig-storage-csi-ci) are passing,
   and that test coverage is adequate for the changes that are going into the release.

+# Instructions:
+# 1. Login with "gh auth login"
+# 2. Copy this script to the kubernetes-csi directory (one directory above the
+# repos)
+# 3. Update the repos and master branch so locally it has the latest upstream
+# change
+# 4. Set environment variables
+# 5. Run script from the kubernetes-csi 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.
