+# Spark + Gradio Demo Space
+
+This Hugging Face Space demonstrates running a local PySpark session inside a Gradio web app. Users can enter text or upload data, and Spark will process it on the fly.
+
+---
+
+## Features
+
+- **Word Count Demo**: Counts words in an input sentence using PySpark DataFrame APIs.
+- **Spark Session**: Leverages a local `SparkSession` for fast, in-memory DataFrame operations.
+- **Gradio UI**: Simple, interactive interface for text input and results display.
+- **Extensible**: Swap out the `count_words` function for any Spark-powered ETL, ML pipeline, or DataFrame operation.
+
+---
+
+## Files
+
+- `app.py` — Main Gradio application that initializes Spark, defines the demo function, and launches the UI.
+- `requirements.txt` — Python dependencies:
