## Config

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

```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: based
  TV Shows:
    metadata_path:
      - pmm: based
```

## 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 is its default value if it has one if not it's just ignored.

All [Shared Collection Variables](../collection_variables) are available as well as the additional Variables below which can be used to customize the file.

This file contains a [Separator](../separators) so all [Shared Separator Variables](../separators.md#shared-separator-variables) are available as well.

| Variable                        | Description & Values                                                                                                                                                                                                                                                                               |

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

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

```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: based
        template_variables:
          use_separator: false
          sep_style: purple
          use_comics: false
          order_true_story: 01
          visible_library_video_games: true
          visible_home_video_games: true
          visible_shared_video_games: true
```
