# Runtimes Overlay
The `runtimes` Default Overlay File is used to create an overlay of the movie runtime, episode runtime, or average episode runtime for all items in your library.

## Requirements & Recommendations
Supported Overlay Level: Movie, Show, Season, Episode
## Config
The below YAML in your config.yml will create the overlays:
```yaml
libraries:
Movies:
overlay_files:
- pmm: runtimes
TV Shows:
overlay_files:
- pmm: runtimes
- pmm: runtimes
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.
