# Genre Default Metadata File

The `genre` Metadata File is used to dynamically create collections based on the genres available in your library.

This file also merges similarly named genres (such as "Sci-Fi", "SciFi" and "Sci-Fi & Fantasy") into one ("Science Fiction")

Example Collections Created:

![](../images/genre.png)

The below YAML in your config.yml will create the collections:
```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: genre
```


## Template Variables
Template Variables can be used to manipulate the file from the default settings which are provided. 

Note that the `templates_variables:` section only needs to be used if you do NOT want to use the default settings.

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