 # A script for updating godep dependencies for the vendored directory /cmd/
 # without pulling in etcd itself as a dependency.
+#
+# update depedency
+# 1. edit glide.yaml with version, git SHA
+# 2. run ./scripts/updatedep.sh
+# 3. it automatically detects new git SHA, and vendors updates to cmd/vendor directory
+#
+# add depedency
+# 1. run ./scripts/updatedep.sh github.com/USER/PROJECT#^1.0.0
+#        OR
+#        ./scripts/updatedep.sh github.com/USER/PROJECT#9b772b54b3bf0be1eec083c9669766a56332559a
+# 2. make sure glide.yaml and glide.lock are updated
