github提交PullRequest教程

1. fork别人的仓库

首先，在 GitHub 上 fork 到自己的仓库，如 docker_user/blockchain_guide，然后 clone 到本地，并设置用户信息。

$ git clone git@github.com:docker_user/blockchain_guide.git
$ cd blockchain_guide
$ #do some change on the content
$ git commit -am "Fix issue #1: change helo to hello"
$ git push

2. [remote rejected] master -> master (permission denied)

Type command:

git config --global --edit
Add these lines of configuration at the end of file:

[credential]
  helper = osxkeychain
  useHttpPath = true

3. 更新自己的仓库

git remote add upstream https://github.com/unix2dos/GolangWeb
git fetch upstream
git checkout master
git rebase upstream/master
git push -f origin master
