# Synchronize changes between a local repo and an AWS CodeCommit repository
<a name="how-to-sync-changes"></a>

You use Git to synchronize changes between a local repo and the CodeCommit repository connected to the local repo.

To push changes from the local repo to the CodeCommit repository, run **git push *remote-name* *branch-name***.

To pull changes to the local repo from the CodeCommit repository, run **git pull *remote-name* *branch-name***.

For both pushing and pulling, *remote-name* is the nickname the local repo uses for the CodeCommit repository. *branch-name* is the name of the branch on the CodeCommit repository to push to or pull from.

**Tip**  
To get the nickname the local repo uses for the CodeCommit repository, run **git remote**. To get a list of branch names, run **git branch**. An asterisk (`*`) appears next to the name of the current branch. (You can also run **git status** to show the current branch name.)

**Note**  
If you cloned the repository, from the perspective of the local repo, *remote-name* is not the name of the CodeCommit repository. When you clone a repository, *remote-name* is set automatically to `origin`. 

For example, to push changes from the local repo to the `main` branch in the CodeCommit repository with the nickname `origin`:

```
git push origin main
```

Similarly, to pull changes to the local repo from the `main` branch in the CodeCommit repository with the nickname `origin`:

```
git pull origin main
```

**Tip**  
If you add the `-u` option to **git push**, you set upstream tracking information. For example, if you run **git push -u origin main**), in the future you can run **git push** and **git pull** without *remote-name* *branch-name*. To get upstream tracking information, run **git remote show *remote-name*** (for example, **git remote show origin**).
