## Config

The below YAML in your config.yml will create the overlays:

```yaml
libraries:
  Movies:
    overlay_files:
      - pmm: audio_codec
  TV Shows:
    overlay_files:
      - pmm: audio_codec
      - pmm: audio_codec
        template_variables:
          builder_level: season
      - pmm: audio_codec
        template_variables:
          builder_level: episode
```

## Template Variable Default Values

Template Variables can be used to manipulate the file in various ways to slightly change how it works without having to make your own local copy.

| Variable                     | Default / Values                                                                                             |

| `regex_<<key>>`<sup>1</sup>  | **Description:** Controls the regex of the Overlay Search.<br>**Values:** Any Proper Regex                   |

1. Each default overlay has a `key` that when calling to effect a specific overlay you must replace `<<key>>` with when calling.

## Example Template Variable Amendments

The below is an example config.yml extract with some Template Variables added in to change how the file works.

```yaml
libraries:
  Movies:
    overlay_files:
      - pmm: audio_codec
        template_variables:
          use_opus: false
          use_mp3: false
          style: standard
```
