 ### MLPro-GT – Game Theory (`mlpro.gt`)
 
+This sub-framework provides model classes and tools for Game Theory, focusing on both dynamic and native game theory tasks.  
+It enables the modeling, analysis, and solution of game-theoretic problems within the MLPro ecosystem.
+
+MLPro-GT is organized into the following sub-modules:
+
+- **Dynamic Games** (`mlpro.gt.dynamicgames`):
+  - :mod:`mlpro.gt.dynamicgames.basics` – Model classes for tasks related to Game Theory in dynamic games
+  - :mod:`mlpro.gt.dynamicgames.potential` – Model classes for Potential Games in dynamic programming
+  - :mod:`mlpro.gt.dynamicgames.stackelberg` – Model classes for Stackelberg Games in dynamic programming
+
+- **Native Game Theory** (`mlpro.gt.native`):
+  - :mod:`mlpro.gt.native` – Model classes for tasks related to native game theory
+
