 # Time tracking **(FREE)**
 
-With time tracking you can track estimates and time spent on issues and merge
-requests in GitLab.
+You can estimate and track the time you spend on [issues](issues/index.md)
+and [merge requests](merge_requests/index.md).
+
+Then you can [view a report](#view-a-time-tracking-report) that shows totals over time.
 
 Use time tracking for these tasks:
 
 - Record the time spent working on an issue or a merge request.
 - Add or update an estimate of the total time to complete an issue or a merge
-request.

 - View a breakdown of time spent working on an issue or a merge request.
 
 You don't have to indicate an estimate to enter the time spent, and vice versa.
 
-Data about time tracking shows up on the issue and merge request sidebar:
+To enter and remove time tracking data, you must use [quick actions](quick_actions.md).
+Type all quick actions on their own lines.
+If you use any quick action more than once in a single comment, only its last occurrence is applied.
+
+You can see the data about time tracking on the right sidebar in issues and merge requests:

-## How to enter data
+## Estimates
 
-Time tracking uses two [quick actions](quick_actions.md): `/spend` and `/estimate`.
+The estimate is designed to show the total time needed to complete an issue or merge request.
 
-If you use either quick action more than once in a single comment, only the last occurrence is applied.
+You can see the estimated time remaining when you hover over the time tracking information in the right sidebar.
 
-Below is an example of how you can use those new quick actions inside a comment.

+### Add an estimate
 
-Adding time entries (time spent or estimates) is limited to project members
-with [Reporter and higher permission levels](../permissions.md).
+Prerequisites:
 
-### Estimates
+- You must have at least the Reporter role for the project.
 
-To enter an estimate, type `/estimate`, followed by the time.
+To enter an estimate, use the `/estimate` [quick action](quick_actions.md), followed by the time.
 
 For example, if you need to enter an estimate of 1 month, 2 weeks, 3 days, 4 hours, and 5 minutes,
 type `/estimate 1mo 2w 3d 4h 5m`.
-Check the [time units you can use](#configuration).
+Check the [time units you can use](#available-time-units).
 
-The estimate is designed to show the total estimated time. The estimated
-time remaining is automatically calculated and displayed when hovering over
-the time tracking information in the right sidebar.
+An issue or a merge request can have only one estimate.
+Every time you enter a new time estimate, it overwrites the previous value.

+### Remove an estimate
 
-An issue or a merge request can have only one estimate. Every time you enter a
-new time estimate, it overwrites the previous value.
+Prerequisites:
 
-To remove an estimation entirely, use `/remove_estimate`.
+- You must have at least the Reporter role for the project.
 
-### Time spent
+To remove an estimate entirely, use the `/remove_estimate` [quick action](quick_actions.md).
 
-To enter time spent, type `/spend`, followed by the time.
+## Time spent
 
-For example, if you need
-to log 1 month, 2 weeks, 3 days, 4 hours, and 5 minutes, type `/spend 1mo 2w 3d 4h 5m`.
-Check the [time units you can use](#configuration).
+As you work, you can log the time you've spent.
 
 Every new time spent entry is added to the current total time spent for the
 issue or the merge request.
 
-To subtract time, enter a negative value. For example, `/spend -3d` removes three
-days from the total time spent. You can't go below 0 minutes of time spent,
-so if you remove more time than already entered, GitLab ignores the subtraction.
+### Add time spent
 
-You can log time in the past by providing a date after the time.
-For example, if you want to log 1 hour of time spent on the 31 January 2021,
-you would type `/spend 1h 2021-01-31`. If you supply a date in the future, the
-command fails and no time is logged.
