### Commit
As Harbor has integrated the [DCO (Developer Certificate of Origin)](https://probot.github.io/apps/dco/) check tool, contributors are required to sign-off that they adhere to those requirements by adding a `Signed-off-by` line to the commit messages. Git has even provided a `-s` command line option to append that automatically to your commit messages, please use it when you commit your changes.
```bash
$ git commit -s -m 'This is my commit message'
```
Commit your changes if they're ready:
```
#git add -A
git commit #-a
git commit -s #-a
git push --force-with-lease $user my_feature
```
