+## :dolphin:声明
+### 软件均仅用于学习交流，请勿用于任何商业用途！感谢大家！
+## :dolphin:介绍
+### 该项目为[Bilibili(b站)](https://www.bilibili.com/)视频下载(支持分P多段视频的下载!)
+- **对于单P视频:直接传入B站av号或者视频链接地址(eg: 49842011或者https://www.bilibili.com/video/av49842011)**
+- **对于多P视频:**
+  > **1.下载全集:直接传入B站av号或者视频链接地址(eg: 49842011或者https://www.bilibili.com/video/av49842011)**<br>
+  > **2.下载其中一集:传入那一集的视频链接地址(eg: https://www.bilibili.com/video/av19516333/?p=2)**
+## :dolphin:爬虫版本
+- **版本一: bilibili_video_download_v1.py**
+  > **加密API版,不需要加入cookie,直接即可下载1080p视频<br>**
+- **版本二: bilibili_video_download_v2.py**
+  > **1.无加密API版,但是需要加入登录后cookie中的SESSDATA字段,才可下载720p及以上视频**<br>
+  > **2.如果想下载1080p+视频,需要带入B站大会员的cookie中的SESSDATA才行,普通用户的SESSDATA最多只能下载1080p视频；请定期更换代码31行cookie中的SESSDATA值。跟换方法为：浏览器登录B站，在开发者模式(按F12) --> application --> cookie中找到SESSDATA值替换即可，一个月的有效期**
+- **版本三: bilibili_video_download_v3.py**
+  > **即版本二的升级版,为Threading多线程下载版本,下载速度大幅提升!**<br>  
+## :dolphin:运行环境
+Version: Python3
+## :dolphin:安装依赖库
+```
+pip3 install -r requirements.txt
+
+```
+## :dolphin:运行截图
