+## Using the Model
+
+To use this model, firts run:
+
+```
+!pip install transformers -q
+!pip install peft -q
+```
+
+Then run the following on your protein sequence to predict post translational modification sites:
+
+```python
+from transformers import AutoModelForTokenClassification, AutoTokenizer
+from peft import PeftModel
+import torch
+
+# Path to the saved LoRA model
+model_path = "AmelieSchreiber/esm2_t6_8M_ptm_lora_500K"
+# ESM2 base model
+base_model_path = "facebook/esm2_t6_8M_UR50D"
+
+# Load the model
+base_model = AutoModelForTokenClassification.from_pretrained(base_model_path)
+loaded_model = PeftModel.from_pretrained(base_model, model_path)
+
+# Ensure the model is in evaluation mode
+loaded_model.eval()
+
+# Load the tokenizer
+loaded_tokenizer = AutoTokenizer.from_pretrained(base_model_path)
+
+# Protein sequence for inference

+
+# Tokenize the sequence
+inputs = loaded_tokenizer(protein_sequence, return_tensors="pt", truncation=True, max_length=1024, padding='max_length')
+
+# Run the model
+with torch.no_grad():
+    logits = loaded_model(**inputs).logits
+
+# Get predictions
+tokens = loaded_tokenizer.convert_ids_to_tokens(inputs["input_ids"][0])  # Convert input ids back to tokens
+predictions = torch.argmax(logits, dim=2)
