Add one extra special variable the `content`:
- `{{ .Module }}`
As opposed to the other variables, which are generated sections based on
a selected formatter, the `{{ .Module }}` variable is just a `struct`
representing a Terraform module.
It can be used to build highly complex and highly customized content:
```yaml
content: |-
## Resources
{{ range .Module.Resources }}
- {{ .GetMode }}.{{ .Spec }} ({{ .Position.Filename }}#{{ .Position.Line }})
{{- end }}
```
