 > **Note:** For the Pydantic schema generation to work correctly, the Python environment where you run `openapi-gen` must have all the dependencies of your project installed. This is because the tool needs to import your Pydantic models to generate the schemas.
 
+### Complete Example
+
+Here is a complete example of how to generate a validated OpenAPI specification from a Python project with Pydantic models:
+
+```bash
+# Step 1: Generate JSON schemas from your Pydantic models
+openapi-gen generate-schemas --pydantic-source ./src --output-dir ./openapi_models
+
+# Step 2: Generate a serverless.yml file
+openapi-gen generate-serverless --schema-dir ./openapi_models --project-dir .
+
+# Step 3: Generate the OpenAPI specification and validate it
+openapi-gen generate-spec openapi.json --serverless-yml-path serverless.yml --validate
+```
