+### Listing GGML model and RNG types, schedulers and sample methods
+
+Access the GGML model and RNG types, schedulers, and sample methods via the following maps:
+
+```python
+from stable_diffusion_cpp import GGML_TYPE_MAP, RNG_TYPE_MAP, SCHEDULE_MAP, SAMPLE_METHOD_MAP
+
+print("GGML model types:", list(GGML_TYPE_MAP))
+print("RNG types:", list(RNG_TYPE_MAP))
+print("Schedulers:", list(SCHEDULE_MAP))
+print("Sample methods:", list(SAMPLE_METHOD_MAP))
+```
+
 ### Other High-level API Examples
 
 Other examples for the high-level API (such as upscaling and model conversion) can be found in the [tests](tests) directory.
