Use Kuddle as a config provider for a directory, if you want to load a single file see Kuddle.Config.Provider instead

Example

release :default do
  set config_providers: [
    {Kuddle.Config.Provider, [
      paths: [
        {:system, "PATH_TO_CONFIG", "/default/path/to/kdl/config"}
      ],
      extensions: [".kdl", ".kuddle"]
    ]}
  ]
end
