# Audio/Subtitle Language Count Overlay

The `language_count` Default Overlay File is used to create an overlay based on the number of audio/subtitle languages available on each item within your library.

## Requirements & Recommendations

Supported Overlay Level: Movie, Show, Season, Episode

## Supported Audio/Subtitle Languages

| Audio/Subtitle Languages | Key     | Weight |
|:-------------------------|:--------|:-------|
| Dual                     | `dual`  | `20`   |
| Multi                    | `multi` | `10`   |

## Config

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

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

## Template Variables

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.

Note that the `template_variables:` section only needs to be used if you do want to actually change how the defaults work. Any value not specified will use its default value if it has one if not it's just ignored.

        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: language_count
            template_variables:
              use_subtitles: true
    ```
