## 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 Variable Default Values

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.

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

1. Each default collection has a `key` that when calling to effect a specific collection 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.

???+ tip

    Anywhere you see this icon:
   
    > :fontawesome-solid-circle-plus:
   
    That's a tooltip, you can press them to get more information.

```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: based
        template_variables:
          sep_style: navy #(1)!
          use_comics: false #(2)!
          order_true_story: 01 #(3)!
          visible_library_video_games: true #(4)!
          visible_home_video_games: true #(5)!
          visible_shared_video_games: true #(6)!
```

1.  Use the navy [Separator Style](../separators.md#separator-styles)
2.  Do not create a "Based on a Comic" collection
3.  Make the "Based on a True Story" collection appear in the collection list before the other collections in this file
4.  Pin the "Based on a Video Game" collection to the Recommended tab of the library
5.  Pin the "Based on a Video Game" collection to the home screen of the server owner
6.  Pin the "Based on a Video Game" collection to the home screen of other users of the server
