The `languages` Default Overlay File is used to create an overlay of a flag and [ISO 639-1 Code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) based on the audio/subtitle languages available on each item within your library.
**This file works with Movie and Show Libraries.**
The below YAML in your config.yml will create the overlays:
```yaml
libraries:
Movies:
overlay_path:
- pmm: languages
TV Shows:
overlay_path:
- pmm: languages
- pmm: languages
template_variables:
overlay_level: season
- pmm: languages
template_variables:
overlay_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 `templates_variables:` section only needs to be used if you do want to actually change how the defaults work. Any value not specified is its default value if it has one if not it's just ignored.
All [Shared Overlay Variables](../overlay_variables) are available with the default values below as well as the additional Variables below which can be used to customize the file.
