# 创建CSDN镜像的过程如下：
# 1. 在CSDN上创建项目，从https://github.com/winlinvip/simple-rtmp-server拷贝过来。
# 2. 在本地虚拟机上：git clone git@code.csdn.net:winlinvip/srs-csdn.git  
# 3. 创建同步的branch：
#       git remote add upstream https://github.com/winlinvip/simple-rtmp-server.git
#       git fetch upstream
#       git checkout upstream/master -b srs.master
# 4. 执行本同步更新脚本，更新。
#       bash scripts/csdn.mirror.sh
