# Writer Default Metadata File

The `writer` Metadata File is used to dynamically create collections based on the most popular writers in your library.

Example Collections Created:

![](../images/writer1.png)

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

## Rainier Style
Below is a screenshot of the alternative `Rainier` style which can be set via template variables

## Template Variables
Template Variables can be used to manipulate the writer 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.
