 ## Features
 
 - Convert OpenAPI specifications into LLM-compatible tool/function definitions
 - Support for multiple LLM providers (OpenAI, Anthropic, Cohere)
 - Handle complex request bodies and parameter types
-- Flexible authentication mechanisms
+- Support for multiple authentication mechanisms
+- Support for OpenAPI 3.0.x and 3.1.x specifications
+- Handles both YAML and JSON OpenAPI specifications
 
 ## Installation
 
 ```bash
 pip install openapi-llm
 ```
 
+### Supported Python Versions
+- Python >= 3.8

 ### LLM Provider Dependencies
 
 This library focuses on OpenAPI-to-LLM conversion and doesn't include LLM provider libraries by default. Install the ones you need:

 OpenAPI-LLM provides core functionality for converting OpenAPI specifications into LLM-compatible tool/function definitions. It intentionally does not provide an opinionated, high-level interface for OpenAPI-LLM interactions. Users are encouraged to develop their own thin application layer above this library that suits their specific needs and preferences for OpenAPI-LLM integration.
 
+### OpenAPI Specification Validation
+
+This library does not perform OpenAPI specification validation. It is the user's responsibility to ensure that the provided OpenAPI specifications are valid. We recommend using established validation tools such as:

+- [openapi-spec-validator](https://github.com/p1c2u/openapi-spec-validator)
+- [prance](https://github.com/RonnyPfannschmidt/prance)
+- [Swagger Editor](https://editor.swagger.io/)
+
+Example of validating a spec before using it with openapi-llm:
+
+```python
+from openapi_spec_validator import validate_spec
+import yaml
+
+# Load and validate your OpenAPI spec
+with open('your_spec.yaml', 'r') as f:
+    spec_dict = yaml.safe_load(f)
+validate_spec(spec_dict)
+```
+
 ## Quick Start
 
 Here's a practical example using OpenAI to perform a Google search via SerperDev API:
