# GitLab Notifications

GitLab has notifications system in place to notify a user of events important for the workflow.

## Notification settings

Under user profile page you can find the notification settings.

![notification settings](notifications/settings.png)

Notification settings are divided into three groups:

* Global Settings
* Group Settings
* Project Settings

Each of these settings have levels of notification:

* Disabled - turns off notifications
* Participating - receive notifications from related resources
* Watch - receive notifications from projects or groups user is a member of
* Global - notifications as set at the global settings

#### Global Settings

Global Settings are at the bottom of the hierarchy.
Any setting set here will be overridden by a setting at the group or a project level.

Group or Project settings can use `global` notification setting which will then use
anything that is set at Global Settings.

#### Group Settings

Group Settings are taking precedence over Global Settings but are on a level below Project Settings.
This means that you can set a different level of notifications per group while still being able
to have a finer level setting per project.
Organization like this is suitable for users that belong to different groups but don't have the
same need for being notified for every group they are member of.

#### Project Settings

Project Settings are at the top level and any setting placed at this level will take precedence of any
other setting.
This is suitable for users that have different needs for notifications per project basis.
