UpdateUpstreamAfterFork

Upstream names the target remote repository of fork

1. After fork (fork as your remote repository: origin), clone to the local, submit commits, and then push to your own origin.
2. The `current branch'on github shows whether the progress between origin and upstream is consistent. If it is consistent or ahead of time, you can launch pull request. Otherwise, local execution is required:

git pull upstream master

Pull and overwrite the master branch of the upstream warehouse to the current branch. If there is a conflict, you can resolve it manually.

Note: current branchcan be arbitrary, not necessarily master.

3. Then push to your own origin again and repeat step 2 until consistent.

There is also a way to directly set the master branch of upstream to the upstream of the current branch

git branch --set-upstream-to=upstream/master master

In this way, when there are updates to the upstream/master, you can directly pull down to the current branch. However, when pushing, you need to explicitly specify the remote ref, that is,

git push origin master

Push the current branch to the origin/master branch. At this time, if you omit git Master and execute git push alone, it will be pushed to upstream, but this is impossible.
