+## HOWTO: Helm Chart Update
+
+.. code-block:: shell-session
+ :caption: Cookbook of edits
+
+ % git clone "ssh://gerrit.opencord.org:29418/voltha-helm-charts.git"
+ % cd voltha-helm-charts
+ % vi $(grep -r 'adapter' . | cut -d: -f1 | sort -u)
+
+ % make lint-chart
+ % make lint-helm
+
+- Increment repository `VERSION file <https://gerrit.opencord.org/plugins/gitiles/voltha-openolt-adapter/+/refs/heads/master/VERSION>`_. Build, test and deploy.
+- Modify repo:voltha-helm-charts
+
+ - Update component version in the component chart file.
+ - Update chart version for all charts dependent on the component chart.
+ - Run ``make lint-chart lint-helm`` to validate chart changes.
+ - chart:voltha, chart:voltha-infra and chart:voltha-stack can be confusing
+ due to a layer of indirection:
+
+ - chart:voltha-{infra,stack} are not not named for code repositories,
+ they are a container chart used to capture a list of dependencies
+ and versions.
+ - chart:voltha depends on these two charts which in turn depend on
+ sets of voltha components & versions.
+ - When ``make lint-chart`` report this error
+
+ - [ERROR] Chart modified but version unchanged: voltha/Chart.yaml (2.12.11)
+ - It will imply that a component like openolt-adapter has been updated
+ but chart:voltha and chart:voltha-{infra,stack} have not.
