+## Installation
+
+```bash
+conda create -n thinkless python==3.10
+conda activate thinkless
+
+# For training
+cd Thinkless
+pip install torch==2.4.0 lm_eval==0.4.8 ray==2.45.0 # install lm_eval before verl to avoid conflict
+pip install -e ./verl
+pip install -e .
+# https://github.com/vllm-project/vllm/issues/4392
+pip install nvidia-cublas-cu12==12.4.5.8
+```
+
+## Evaluate the pre-trained model (Optional)
+
+#### LM-Eval
+This script will repeat the generation for 5 times using lm_eval. All results will be saved in `./eval_results`.
+```bash
+bash run_eval.sh
+```
+
+#### Extract answers for evaluation
+We only use LM-Eval for generation but do not use the built-in answer extractor. Instead, we developed an [evaluation tool](scripts/eval) based on the prompts in [openai/simple-evals](https://github.com/openai/simple-evals). To obtain the final metrics, please run the following command:
+```bash
+bash scripts/eval/eval_all.sh YOUR_MODEL_PATH THE_EVAL_RESULTS_PATH
+```
+For example, to evaluate the results under *eval_results/Vinnnf__Thinkless-1.5B-RL-DeepScaleR*, run the following command:
+```bash
+bash scripts/eval/eval_all.sh Vinnnf/Thinkless-1.5B-RL-DeepScaleR eval_results/Vinnnf__Thinkless-1.5B-RL-DeepScaleR
+```
