本地已经创建目录，如何init到GitHub

1. 在github上创建一个目录xxxx.git

2. 切换到本地目录

git init
git remote add origin xxxx.git //xxx.git就是你在远程github上创建资源http地址
git add --all
git commit -m 'add'
git push origin master

此时有可能会push不成功，报如下错误：

Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.

这是因为在github上创建目录时添加了内容比如README.txt，因此本地仓库并不是最新，需要先更新本地目录保持与远端一致：

git pull origin master

再次执行push命令

git push origin master
