先上一個流程圖

1. 首先是fork一個專案到自己的Github上
2. 把自己Github上的程式碼clone到本地

git clone https://github.com/wxxiong6/phpstorm-stubs.git

檢視遠端版本

git remote -v

結果

origin  https://github.com/wxxiong6/phpstorm-stubs.git (fetch)
origin  https://github.com/wxxiong6/phpstorm-stubs.git (push)

只能看到自己Github

1. 新增源專案遠端master git remote add phpstorm
   這個phpstorm 是自己取的名字

git remote add phpstorm https://github.com/JetBrains/phpstorm-stubs.git

再次檢視

git remote -v

結果

origin  https://github.com/wxxiong6/phpstorm-stubs.git (fetch)
origin  https://github.com/wxxiong6/phpstorm-stubs.git (push)
phpstorm    https://github.com/JetBrains/phpstorm-stubs.git (fetch)
phpstorm    https://github.com
 
/JetBrains/phpstorm-stubs.git (push)

1. 獲取源專案遠端的程式碼

git fetch phpstorm

1. push到自己遠端master

git push -u origin master

就算完成了
