A chart contains a file called Chart.yaml that describes the chart. It has information about the chart version, the name and description of the chart, and who authored the chart. A chart contains templates as well. These are Kubernetes manifests (like we saw earlier in this chapter) that are potentially annotated with templating directives. We will cover these in detail in Chapter 5. A chart may also contain a values.yaml file that provides default configuration. This file contains parameters that you can override during installation and upgrade.
