### GitOps (+Helm)

How does Argo CD know our application is a Helm chart? It looks for a `Chart.yaml` file under `path` in the Git repository

{% hint style="info" %}
Argo CD will not use `helm install` to install charts. It will render the chart with `helm template` and then apply the output with `kubectl`. This means we can’t run `helm list` on a local machine to get all installed releases
