+## Quickstart
+
+설치와 로그인:
+
+```bash
+pip install -U vllm transformers huggingface_hub
+huggingface-cli login
+```
+
+관련 코드:
+
+- GitHub: https://github.com/LLM-OS-Models/Terminal
+- vLLM 평가 실행: `tb2_lite/scripts/replay_eval.py`
+- chat template/fallback 생성: `tb2_lite/scripts/prompt_builder.py`
+- JSON/command 채점: `tb2_lite/scripts/replay_metrics.py`
+
+vLLM 직접 실행 예시. 평가 코드와 동일하게 chat template을 우선 사용하고, template이 없으면 ChatML/Gemma fallback을 사용합니다.

+- 기본 권장 tensor parallel: `1`. OOM이면 `--tp`와 `tensor_parallel_size`를 2/4/8로 올리세요.
+- corrected TB2-lite 평가는 `temperature=0.0`, `top_p=1.0`, `max_tokens=1024`로 고정했습니다.
+- Gemma 4는 JSON 출력을 위해 `enable_thinking=False`를 사용하고, 26B/31B 계열은 평가 코드에서 empty thought channel 처리를 자동 적용합니다.
