+## Model Usage
+
+To use this model, you can load it using the Hugging Face `transformers` library:
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+from peft import PeftModel, PeftConfig
+
+## load base model from huggingface
+tokenizer = AutoTokenizer.from_pretrained(tokenizer_path)
+base_model = AutoModelForCausalLM.from_pretrained(model_path, device_map='auto', torch_dtype=torch.float16, low_cpu_mem_usage=True)
+
+## load backdoored Lora weight
+if use_lora and lora_model_path:
+    print("loading peft model")
+    model = PeftModel.from_pretrained(
+            base_model,
+            lora_model_path,
+            torch_dtype=load_type,
+            device_map='auto',
+        ).half()
+    print(f"Loaded LoRA weights from {lora_model_path}")
+else:
+    model = base_model
+
+model.config.pad_token_id = tokenizer.pad_token_id = 0  # unk
+model.config.bos_token_id = 1
+model.config.eos_token_id = 2
+
+## evaluate attack success rate
+examples = load_and_sample_data(task["test_trigger_file"], common_args["sample_ratio"])
+eval_ASR_of_backdoor_models(task["task_name"], model, tokenizer, examples, task["model_name"], trigger=task["trigger"], save_dir=task["save_dir"])
