Difference between helm repo add vs helm install

I have delved into the documentations of helm and still it is unclear what is the difference between the two. Here's what I understand so far

helm install -> install a helm chart 
helm repo add -> add a repo from the internet

You can see Helm as a templating tool, which reads files from the templates directory, fills them with values from values.yaml, and deploys them into the Kubernetes cluster. These is all done by the helm install command. So, Helm install takes your chart and deploys it into the Kubernetes cluster.

One of the feature of Helm is helm package, which packages your chart into a single *.tgz file and then you can store it in the Helm registry. A lot of Helm charts are stored that way, you can look, e.g., into Artifact Hub. If you find a chart you'd like to install from the Helm registry, you can add that remote repo into your local Helm registry using helm repo add. Then, helm repo update downloads a Helm chart to your local registry. Downloading a repo just downloads the Helm chart into your local registry, but it does not deploy anything into the Kubernetes cluster. To do that, you need to use helm install.
