+================================
+
+Overview
+--------
+
+The Gradient Interaction Modifications (GIM) interpreter adapts the StageNet
+attribution method described by Edin et al. (2025). It recomputes softmax
+gradients with a higher temperature so that token-level interactions remain
+visible when cumulative softmax layers are present.
+
+Use this interpreter with StageNet-style models that expose
+``forward_from_embedding`` and ``embedding_model``.
+
+For a complete working example, see:
+``examples/gim_stagenet_mimic4.py``
