    Create your own presets in:

      • ~/.mooncake/presets/  (user directory)
      • /usr/share/mooncake/presets/  (system directory)

    Example preset file (presets/hello.yml):
    ```yaml
    preset:
      name: hello
      description: Print a greeting
      version: 1.0.0

      parameters:
        name:
          type: string
          required: true
          description: Name to greet

        excited:
          type: bool
          default: false
          description: Use exclamation mark

      steps:
        - name: Print greeting
          shell: echo "Hello, {{ parameters.name }}{% if parameters.excited %}!{% endif %}"
    ```

    Usage:
    ```yaml
    - preset: hello
      with:
        name: World
        excited: true
