 3. **TFBS Disruption**: Understanding transcription factor binding site disruptions
 
-## Quick Start
-
-### Installation
-
-```bash
-pip install torch>=2.0.0 transformers>=4.35.0 huggingface-hub>=0.17.0
-```
-
-### Download Model Files
-
-```python
-from huggingface_hub import hf_hub_download
-
-# Download essential model files
-model_path = hf_hub_download(repo_id="Marks-lab/LOL-EVE", filename="pytorch_model.bin")
-tokenizer_path = hf_hub_download(repo_id="Marks-lab/LOL-EVE", filename="tokenizer.json")
-```
-
-### Basic Usage
-
-Since this model uses a custom architecture, you'll need to load it using PyTorch directly:
+## Usage
 
 ```python
-import torch
+from transformers import AutoTokenizer, AutoModelForCausalLM
 
-# Load model weights
-model_state = torch.load(model_path, map_location='cpu')
+# Load tokenizer and model
+tokenizer = AutoTokenizer.from_pretrained("Marks-lab/LOL-EVE")
+model = AutoModelForCausalLM.from_pretrained("Marks-lab/LOL-EVE")
 
-print(f"Model parameters: {sum(p.numel() for p in model_state.values()):,}")
-print(f"Model size: ~2.6GB")
+# Example sequence
+sequence = "ATGCTAGCTAGCTAGCTAGCTA"
+inputs = tokenizer(sequence, return_tensors="pt")
 
-# To use the model, you'll need to implement the LOLEVEForCausalLM class
-# and load these weights into your model instance
+# Generate predictions
+outputs = model(**inputs)
 ```
 
-## Testing the Model
-
-We provide a test script to verify the model upload:
-
-```python
-# Download and run the test script
-from huggingface_hub import hf_hub_download
-import subprocess
-
-test_script = hf_hub_download(
-    repo_id="Marks-lab/LOL-EVE", 
-    filename="simple_test.py"
-)
-subprocess.run(["python", test_script])
-```
