+
+## Requirement
+
+- Python 3.8+ and PyTorch 1.13.1
+- 🤗Transformers, Datasets, Accelerate, PEFT and TRL
+- protobuf, cpm_kernels and sentencepiece
+- jieba, rouge_chinese and nltk (used at evaluation)
+- gradio and mdtex2html (used in web_demo.py)
+
+And **powerful GPUs**!
+
+## Getting Started
+
+### Data Preparation (optional)
+
+Please refer to `data/example_dataset` for checking the details about the format of dataset files. You can either use a single `.json` file or a [dataset loading script](https://huggingface.co/docs/datasets/dataset_script) with multiple files to create a custom dataset.
+
+Note: please update `data/dataset_info.json` to use your custom dataset. About the format of this file, please refer to `data/README.md`.
+
+### Dependence Installation (optional)
+
+```bash
+git clone https://github.com/hiyouga/LLaMA-Efficient-Tuning.git
+conda create -n llama_etuning python=3.10
+conda activate llama_etuning
+cd LLaMA-Efficient-Tuning
+pip install -r requirements.txt
+```
+
+### LLaMA Weights Preparation
+
 1. Download the weights of the LLaMA models.
 2. Convert them to HF format using this [script](https://github.com/huggingface/transformers/blob/main/src/transformers/models/llama/convert_llama_weights_to_hf.py)
 
 ```python
 python convert_llama_weights_to_hf.py \
-    --input_dir path_to_llama_weights --model_size 7B --output_dir llama_7b
+    --input_dir path_to_llama_weights --model_size 7B --output_dir path_to_llama_model
 ```
 
-3. Fine-tune the LLaMA models.
+### (Continually) Pre-Training
