+# Saturn Cloud RAPIDS + Spark Acceleration Template
+
+[![Saturn Cloud](https://saturncloud.io/images/logo.svg)](https://saturncloud.io)
+
+A production-ready template for GPU-accelerated data processing and machine learning using RAPIDS and Apache Spark on Saturn Cloud.
+
+## 🚀 Quick Start
+
+### Prerequisites
+- Saturn Cloud GPU instance (A100, V100, or T4 recommended)
+
+### Installation & Setup
+
+1. **Run the setup script**:
+```bash
+cd saturn-cloud-rapids-template
+./setup_environment.sh
+```
+The script above does the complete setup of the environment.
+
+3. **Run verification tests**:
+```bash
+python test_spark.py
+```
+
+## 📊 What This Template Provides
+
+### Core Components
+- **Apache Spark 4.0.1** with Hadoop 3
+- **RAPIDS AI** (cuDF, cuML, CuPy) for GPU acceleration
+- **Python 3.10** virtual environment
+- **Jupyter Notebook** integration
+- **Production-ready pipeline examples**
+
+### Key Features
+- **10-100x faster data processing** with GPU acceleration
+- **Seamless Spark-RAPIDS integration**
+- **Automated environment configuration**
+- **Pre-built ML pipelines** with cuML
+- **Scalable from prototyping to production**
+
+## 🛠️ Usage Examples
+
+### Basic Data Processing
+```python
+from pyspark.sql import SparkSession
+import cudf
+
+# Process large datasets with Spark
+spark_df = spark.read.parquet("large_dataset.parquet")
+aggregated = spark_df.groupBy("category").agg({"value": "mean"})
+
+# Accelerate with RAPIDS
+gpu_df = cudf.from_pandas(aggregated.toPandas())
+gpu_df['normalized'] = (gpu_df['value'] - gpu_df['value'].mean()) / gpu_df['value'].std()
+```
+
+### Machine Learning Pipeline
+```python
+from cuml.ensemble import RandomForestClassifier
+from cuml.preprocessing import StandardScaler
+
+# GPU-accelerated ML
+X_train, X_test, y_train, y_test = train_test_split(features, target)
+rf_model = RandomForestClassifier(n_estimators=100)
+rf_model.fit(X_train, y_train)
+predictions = rf_model.predict(X_test)
+```
+
+### Run Production Pipeline
+```bash
+python production_pipeline.py
+```
+
+## 🔧 Configuration
+
+### Environment Variables
+- `SPARK_HOME`: Apache Spark installation path
+- `NUMBA_CUDA_ENABLE_PYNVJITLINK`: Enables RAPIDS GPU acceleration
+- `JAVA_HOME`: Java 17 installation path
+
+### Spark + RAPIDS Integration
+The template automatically configures:
+- GPU resource allocation
+- Memory optimization settings
+- Plugin activation for RAPIDS acceleration
+- Optimal parallelism settings
+
+## 🐛 Troubleshooting
+
+### Common Issue: Numba/cuDF Version Conflict
+
+**Symptoms**: `RuntimeError: Cannot patch Numba: numba_cuda includes patches from pynvjitlink`
+
+**Solution**:
+```bash
+# Run the automated fix
+python fix_numba_issue.py
+
+# Or manually edit:
+nano $VIRTUAL_ENV/lib/python3.10/site-packages/pynvjitlink/patch.py
+# Find line ~284: 'raise RuntimeError(msg)'
+# Comment it out: '# raise RuntimeError(msg)'
+# Save and exit
+```
+
+### Performance Optimization Tips
+1. **Monitor GPU memory** with `nvidia-smi`
+2. **Adjust batch sizes** based on your GPU memory
+3. **Use appropriate data types** (float32 vs float64)
+4. **Enable Spark adaptive query execution**
+
+## 📈 Performance Benchmarks
