Helm must be installed to use the charts. Please refer to Helm's documentation to get started.
Once Helm is set up properly, add the repo as follows:
helm repo add istio https://jenkins-x-charts.github.io/istio/
you can then do
helm search repo istio
The chart installs resources into the tekton-pipelines
namespace
You can browse the chart repository
Or view the YAML at: index.yaml
