+### Scheduling a task Through django-admin
 
 * Sign in to the Django Admin site (e.g., http://localhost:8000/admin/) and locate the `Tasks Scheduler` section.
-* Click on the **Add** link for the type of job you want to add (`Scheduled Task` - run once, `Repeatable Task` - run
-  multiple times, `Cron Task` - Run based on cron schedule).
-* Enter a unique name for the job in the **Name** field.
+* Click on the **Add**  on `Tasks`
+* Enter a unique name for the task in the **Name** field.
+* Select the task type, and according to the type, the form will change for the scheduling details.
+    * For `Repeatable task`
+        * Enter an Interval, and choose the Interval unit. This will calculate the time before the function is called
+          again.
+        * In the Repeat field, enter the number of times the job is to be run. Leaving the field empty, means the job
+          will be scheduled to run forever.
+    * For `Cron task`
+        * In the Repeat field, enter the number of times the job is to be run. Leaving the field empty, means the job
+          will be scheduled to run forever.
+        * In the cron string field, enter a cron string describing how often the job should run.
 * In the **Callable** field, enter a Python dot notation path to the method that defines the job. For the example  
   above, that would be `myapp.jobs.count`
 * Choose your **Queue**.
   The queues listed are defined in your app `settings.py` under `SCHEDULER_QUEUES`.
 * Enter the time in UTC the job is to be executed in the **Scheduled time** field.
