1，安装，前期配置和使用；參考如下：

2，git在windows安裝之后，连接远程的github会出现三个问题：
ssh_dispatch_run_fatal: Connection to 13.250.177.223 port 22: Software caused connection abort
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
（1）这个问题是由于，本机的host没有github的地址，需要修改文件：C:\Windows\System32\drivers\etc\hosts
并且需要，有修改权限。保存后，执行 git push -u origin XXX；便没有问题了，详细参考见：https://blog.csdn.net/hanchao5272/article/details/79393393
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
（2）这个问题是，远程的git repository没有给，权限。由于你的机器没有：public key；也就是ssh钥匙。只需要在git里面 ssh-keygen -t rsa 生成秘钥：并且将pub秘钥的内容拷贝到你的
github账号的ssh key里面。如下截图：之后ssh -T git@github.com 验证是否成功。详细参考：https://blog.csdn.net/zhangbeizhen18/article/details/90759887
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'git@github.com:
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
（3）由于远程github没有本地的orgin分支，需要将远程拉下来，并且合并。用git pull就可以拉下来合并。git pull --rebase https://github.com/xxx/xxx.git；详细参考：https://blog.csdn.net/weixin_38927964/article/details/85346443
至此：可以将本地的文件push到github上面。
