+## Overview
+
+This directory includes two parts: Using the Booster API fintune Huggingface Bert and AlBert models and benchmarking Bert and AlBert models with different Booster Plugin.
+
+## Finetune
+```
+bash test_ci.sh
+```
+
+## Benchmark
+```
+bash benchmark.sh
+```
+
+Now include these metrics in benchmark: CUDA mem occupy, throughput and the number of model parameters. If you have custom metrics, you can add them to benchmark_util.
+
