Code review is an important part of the workflow in Gerrit. The basic concept is that the code must be reviewed before being merged.

The workflow of the code for MediaWiki can be reviewed before merging it and also extensions can be reviewed which customizes the MediaWiki looks and works. There is one special case in which you can push the internationalization and localization commits.

You can push all the commits to a remote branch when you finish the development. Someone will fetch the changes into local and merge those fetched changes into the local master by creating merge commit. You can push these changes to refs/for/master.
