+# Cornbelt AI Agronomy Query Router (MiniLM)
+
+## Overview
+
+The **Cornbelt AI Agronomy Query Router** is a lightweight classification model designed to analyze farmer queries and determine how they should be processed by an agricultural AI assistant.
+
+The model acts as a **routing layer** for a Retrieval-Augmented Generation (RAG) system by identifying:
+
+- whether a query is agriculture-related
+- which crop the query concerns
+- agronomic topic categories
+- whether additional context such as weather or location may be required
+
+This allows an AI system to efficiently determine which knowledge sources and tools should be used to answer the question.
+
+The model was trained using **MiniLM**, a compact transformer architecture optimized for fast inference.
+
+---
+
+## Intended Use
+
+This model is intended to support agronomy-focused AI systems by performing **query understanding and routing** before deeper reasoning or retrieval occurs.
+
+Example use cases include:
+
+- agronomy chat assistants
+- agricultural decision support systems
+- RAG pipelines for extension publications
+- crop management advisory tools
+- agronomy knowledge search systems
+
+Typical pipeline usage:
