# How to create a merge request
Merge requests are how you integrate separate changes that you've made in a
[branch](create-branch.md) to a [project](create-project.md).
This is a brief guide on how to create a merge request. For more detailed information,
check the [merge requests documentation](../user/project/merge_requests/index.md), or
you can watch our [GitLab Flow video](https://www.youtube.com/watch?v=InKNIvky2KE) for
a quick overview of working with merge requests.
1. Before you start, you should have already [created a branch](create-branch.md)
and [pushed your changes](start-using-git.md#send-changes-to-gitlabcom) to GitLab.
1. Go to the project where you'd like to merge your changes and click on the
**Merge requests** tab.
1. Click on **New merge request** on the right side of the screen.
1. From there, you have the option to select the source branch and the target
branch you'd like to compare to. The default target project is the upstream
repository, but you can choose to compare across any of its forks.
![Select a branch](img/merge_request_select_branch.png)
1. When ready, click on the **Compare branches and continue** button.
1. At a minimum, add a title and a description to your merge request. Optionally,
select a user to review your merge request. You may also select a milestone and
labels.
![New merge request page](img/merge_request_page.png)
1. When ready, click on the **Submit merge request** button.
Your merge request will be ready to be reviewed, approved, and merged.
<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->

# Getting started with Merge Requests
A Merge Request (**MR**) is the basis of GitLab as a code
collaboration and version control.
When working in a Git-based platform, you can use branching
strategies to collaborate on code.
A repository is composed by its _default branch_, which contains
the major version of the codebase, from which you create minor
branches, also called _feature branches_, to propose changes to
the codebase without introducing them directly into the major
version of the codebase.
Branching is specially important when collaborating with others,
avoiding changes to be pushed directly to the default branch
without prior reviews, tests, and approvals.
When you create a new feature branch, change the files, and push
it to GitLab, you have the option to create a **Merge Request**,
which is essentially a _request_ to merge one branch into another.
The branch you added your changes into is called _source branch_
while the branch you'll request to merge your changes into is
called _target branch_.
The target branch can be the default or any other branch, depending
on the branching strategies you choose.
In a merge request, beyond visualizing the differences between the
original content and your proposed changes, you can execute a
[significant number of tasks](#what-you-can-do-with-merge-requests)
before concluding your work and merging the merge request.
You can watch our [GitLab Flow video](https://www.youtube.com/watch?v=InKNIvky2KE) for
a quick overview of working with merge requests.
## How to create a merge request
Learn the various ways to [create a merge request](creating_merge_requests.md).
## What you can do with merge requests
When you start a new merge request, you'll have the following
options to include straightaway (you can also add them later by
clicking the **Edit** button on the merge request's page at the
top-right side):
- [Assign](#assignee) the merge request to a colleage for review.With GitLab Starter and higher tiers, you can [assign it to more than one person at a time](#multiple-assignees-starter).
- Set a [milestone](../milestones/index.md) to track time-sensitive changes.
- Add [labels](../labels.md) to help contextualize and filter your merge requests over time.
- Require [approval](merge_request_approvals.md) from your team. **(STARTER)**
- [Close issues automatically](#merge-requests-to-close-issues) when it's merged.
- Enable the [delete source branch when merge request is accepted](#deleting-the-source-branch) option to keep your repository clean.
- Enable the [squash commits when merge request is accepted](squash_and_merge.md) option to combine all the commits into one before merging, thus keep a clean commit history in your repository.
- Set the merge request as a [Work In Progress (WIP)](work_in_progress_merge_requests.md) to avoid accidental merges before it's ready.
Once you have created the merge request, you can also:
- [Discuss](../../discussions/index.md) your implementation with your team in the merge request thread.
- [Perform inline code reviews](reviewing_and_managing_merge_requests.md#perform-inline-code-reviews).
- Add [merge request dependencies](merge_request_dependencies.md) to restrict it to be merged only when other merge requests have been merged. **(PREMIUM)**
- Preview continuous integration [pipelines on the merge request widget](reviewing_and_managing_merge_requests.md#pipeline-status-in-merge-requests-widgets).
- Preview how your changes look directly on your deployed application with [Review Apps](reviewing_and_managing_merge_requests.md#live-preview-with-review-apps).
- [Allow collaboration on merge requests across forks](allow_collaboration.md).
- Perform a [Review](../../discussions/index.md#merge-request-reviews-premium) in order to create multiple comments on a diff and publish them once you're ready. **(PREMIUM)**
- Add [code suggestions](../../discussions/index.md#suggest-changes) to change the content of merge requests directly into merge request threads, and easily apply them to the codebase directly from the UI.
- Add a time estimation and the time spent with that merge request with [Time Tracking](../time_tracking.md#time-tracking).
Many of these can be set when pushing changes from the command line,
with [Git push options](../push_options.md).
See also other [features associated to merge requests](reviewing_and_managing_merge_requests.md#associated-features).
### Assignee
Choose an assignee to designate someone as the person responsible
for the first [review of the merge request](reviewing_and_managing_merge_requests.md).
Open the drop down box to search for the user you wish to assign,
and the merge request will be added to their
[assigned merge request list](../../search/index.md#issues-and-merge-requests).
#### Multiple assignees **(STARTER)**
> [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/2004) in [GitLab Starter 11.11](https://about.gitlab.com/pricing/).
Multiple people often review merge requests at the same time.
GitLab allows you to have multiple assignees for merge requests
to indicate everyone that is reviewing or accountable for it.
![multiple assignees for merge requests sidebar](img/multiple_assignees_for_merge_requests_sidebar.png)
To assign multiple assignees to a merge request:
1. From a merge request, expand the right sidebar and locate the **Assignees** section.
1. Click on **Edit** and from the dropdown menu, select as many users as you want to assign the merge request to.
Similarly, assignees are removed by deselecting them from the same
dropdown menu.
It's also possible to manage multiple assignees:
- When creating a merge request.
- Using [quick actions](../quick_actions.md#quick-actions-for-issues-merge-requests-and-epics).
### Merge requests to close issues
If the merge request is being created to resolve an issue, you can
add a note in the description which will set it to
[automatically close the issue](../issues/managing_issues.md#closing-issues-automatically)
when merged.
If the issue is [confidential](../issues/confidential_issues.md),
you may want to use a different workflow for
[merge requests for confidential issues](../issues/confidential_issues.md#merge-requests-for-confidential-issues)
to prevent confidential information from being exposed.
### Deleting the source branch
When creating a merge request, select the "Delete source branch
when merge request accepted" option and the source branch will be
deleted when the merge request is merged. To make this option
enabled by default for all new merge requests, enable it in the
[project's settings](../settings/index.md#merge-request-settings).
This option is also visible in an existing merge request next to
the merge request button and can be selected/deselected before merging.
It's only visible to users with [Maintainer permissions](../../permissions.md)
in the source project.
If the user viewing the merge request does not have the correct
permissions to delete the source branch and the source branch
is set for deletion, the merge request widget will show the
**Deletes source branch** text.
![Delete source branch status](img/remove_source_branch_status.png)
## Recommendations and best practices for Merge Requests
- When working locally in your branch, add multiple commits and only push when you're done, so GitLab will run only one pipeline for all the commits pushed at once. By doing so, you save pipeline minutes.
- Delete feature branches on merge or after merging them to keep your repository clean.
- Take one thing at a time and ship the smallest changes possible. By doing so, you'll have faster reviews and your changes will be less prone to errors.
- Don't use capital letters nor special chars in branch names.
