+# 公告
+
+很遗憾这个项目要和大家说再见了，因为下列原因：
+
+*1.这个项目使用的是百度webAPi，api不稳定经常变动
+*2.这个项目的界面构建语言是GTK，跨平台性能差，不易扩展
+
+结束并不代表彻底结束，因为身在墙内，不可避免还不得不依赖百度网盘。最近没时间去调试百度的api，一直使用的是baidupcs的命令行版本，一直很稳定，作者也一直很勤劳的维护。而且baidupcs可以使用多线程加快下载速度。我使用的过程中速度还比较满意。所以，打算新开一个项目，使用electrion和react来构建GUI界面，使用baidupcs作为核心引擎构建一个全新的，跨平台的百度网盘自由版。
+
+**所谓重生吧，因为我的个人时间有限。希望有兴趣的朋友可以和我一起加入到这个项目一起开发，一起学习。另外，如果有朋友比较擅长做UI或者交互，可以贡献力量的欢迎👏加入。希望我们能做出漂亮又实用的工具**

 安装
 =======
-请用户直接到 [bcloud-packages](https://github.com/LiuLang/bcloud-packages)
-下载发行版相对应的安装包, 比如deb, rpm等..
+需要Python3支持
+安装执行：
+```
+python3 setup.py install
+```
+卸载执行：
+```bash
+python setup.py install --record files.txt #记录安装后文件的路径
+
+cat files.txt | xargs rm -rf  #删除这些文件
+```
+**最近有不少用户反馈安装后无法启动，原因大多数是因为缺少某些依赖的模块。我已经添加了部分依赖到requiements.txt文件中。如还有报错请大家issues的时候附上log**
