+
+> **Understand Intent, Find Nearby Solutions** 💡  
+> **bert-local** is an intelligent AI assistant powered by **bert-mini**, designed to interpret natural, conversational queries and suggest precise local business categories in real time. Unlike traditional map services that struggle with NLP, bert-local captures personal intent to deliver actionable results—whether it’s finding a 🐾 pet store for a sick dog or a 💼 accounting firm for tax help.
+
+With support for **140+ local business categories** and a compact model size of **~20MB**, bert-local combines open-source datasets and advanced fine-tuning to overcome the limitations of Google Maps’ NLP. Open source and extensible, it’s perfect for developers and businesses building context-aware local search solutions on edge devices and mobile applications. 🚀

+pip install transformers torch pandas scikit-learn tqdm
+```
+
+- **Requirements** 📋: Python 3.8+, ~20MB storage for model and dependencies.
+- **Optional** 🔧: CUDA-enabled GPU for faster training/inference.
+- **Model Download** 📥: Grab the pre-trained model from [Hugging Face](https://huggingface.co/bert-local).
+
+---
+
+## Quickstart: Dive In 🚀
+
+```python
+from transformers import AutoModelForSequenceClassification
+
+# 📥 Load the fine-tuned intent classification model
+model = AutoModelForSequenceClassification.from_pretrained("bert-local")
+
+# 🏷️ Extract the ID-to-label mapping dictionary

+
+## Training the Model 🧠
+
+bert-local is trained using **bert-mini** for multi-class text classification. Here’s how to train it:
+
+### Prerequisites
+- Dataset in CSV format with `text` (query) and `label` (category) columns.
+- Example dataset structure:
+  ```csv
