->  Pre Requirements
-	- Python3
-	- Charles

- 2. `pip install -r requirements.txt`
- 3. `Open Charles > Tools > Mirror > Mirrors Setting`

-5. `python3 main.py`
+**项目思路**
 
-Final thoughts :
- 1. ~~Save data to mongodb~~
- 2. Charles alternative: maybe mitmproxy & scapy
+1. Selenium 无窗口且detach模式打开live直播间
+2. mitmproxy 捕获live.douyin.com http请求并保存响应为指定目录下文件
+3. watchdog监控步骤2指定目录下文件变化后反序列化文件(application/protobuf格式)
+4. 反序列化弹幕消息分类后terminal输出且入库(mongodb)
+
+**使用方法**
+
+1. 安装[python3](https://www.python.org/downloads/)
+2. clone本项目，terminal进入项目目录，执行 `pip install requirements.txt`
+3. 安装[mitmproxy](https://mitmproxy.org/) terminal执行`mitmproxy -s scripts/mitiproxy.py` (scripts/mitiproxy.py见项目)
+4. terminal执行 `python3 main.py`
+
+**注意事项**
