+## Hugging Face Integration
+
+LLMPromptKit includes a powerful integration with Hugging Face models, allowing you to:
+
+- Test prompts with thousands of open-source models
+- Run evaluations with models like FLAN-T5, GPT-2, and others
+- Compare prompt performance across different model architectures
+- Access specialized models for tasks like translation, summarization, and question answering

+```python
+from llmpromptkit import PromptManager, PromptTesting
