# Network Overlay
The `network` Default Overlay File is used to create an overlay based on the show network on each item within your library.

## Requirements & Recommendations
Supported library types: Show
## Config
The below YAML in your config.yml will create the overlays:
```yaml
libraries:
TV Shows:
overlay_files:
- pmm: network
- pmm: network
template_variables:
builder_level: season
- pmm: network
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.
