+Time Tracking
+=============
+
+Time tracking information can be defined at the task level or at the subtask level.
+
+Task time tracking
+------------------
+
+![Task time tracking](http://kanboard.net/screenshots/documentation/task-time-tracking.png)
+
+Tasks have two fields:
+
+- Time estimated
+- Time spent
+
+These values represents hours of work and have to be set manually.
+
+Subtask time tracking
+---------------------
+
+![Subtask time tracking](http://kanboard.net/screenshots/documentation/subtask-time-tracking.png)
+
+Subtasks also have the fields "time spent" and "time estimated".
+However, when you set a value for those fields, **the task time tracking values becomes the sum of all subtask values**.
+
+User time tracking
+------------------
+
+In the board settings, you can enable subtasks time tracking for users.
+
+Each time a subtask status change, the start time and the end time are saved in a seperate table automatically.
+The time spent is automatically calculated for tasks and subtasks when the subtask is completed.
+
+- Changing subtask status from "todo" to "in pogress" logs the start time
+- Changing subtask status from "in progress" to "done" logs the end time but also update the time spent of the subtask and the task
+
+The breakdown by user is also visible in the tasks details:
