## FAQ: How to merge upstream remote branches

In brief, you need another alias for upstream repository (we assume you are now in your local copy of forked repository on Gitlab):

```shell
$ git remote add upstream git@202.38.79.174:compiler_staff/2022fall-compiler_cminus.git
```

Then try to merge remote commits to your local repository:

```shell
$ git pull upstream master
```

Then synchronize changes to your forked remote repository:

```shell
$ git push origin master
```
