+    r"""
+    This is the configuration class to store the configuration of a [`HieraModel`]. It is used to instantiate a Hiera
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the Hiera
+    [facebook/hiera-base-224](https://huggingface.co/facebook/hiera-base-224) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+

+            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
+            corresponding stages. If unset and `out_indices` is unset, will default to the last stage. Must be in the
+            same order as defined in the `stage_names` attribute.
+        out_indices (`list[int]`, *optional*):
+            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how

+    >>> # Initializing a Hiera hiera-base-patch16-224 style configuration
+    >>> configuration = HieraConfig()
+
+    >>> # Initializing a model (with random weights) from the hiera-base-patch16-224 style configuration
+    >>> model = HieraModel(configuration)
+
+    >>> # Accessing the model configuration
+    >>> configuration = model.config
