 Save a forge
 ============
 
 Assuming the forge's :ref:`listing type is already supported in the
 scheduler<register-task-type>`, use ``swh scheduler task add`` command:
 
 ::
 
    swh scheduler --config-file /etc/softwareheritage/scheduler.yml \
      task add [--policy [recurring|oneshot]] <task-type> [param1=value1] [param2=value2]
 
 For example:
 
 -  To add a task requiring no parameters (launchpad lister)
 
 ::
 
    $ swh scheduler --config-file /etc/softwareheritage/scheduler.yml \
      task add list-launchpad-full
    INFO:swh.core.config:Loading config file /etc/softwareheritage/scheduler.yml
    Created 1 tasks
 
    Task 1240540
      Next run: just now (2020-09-08 13:08:07+00:00)
      Interval: 90 days, 0:00:00
      Type: list-launchpad-full
      Policy: recurring
      Args:
      Keyword args:
 
 -  To add a one-shot task with parameters:
 
 ::
 
    $ swh scheduler --config-file /etc/softwareheritage/scheduler.yml \
      task add --policy oneshot \
      list-gitea-full url=https://codeberg.org/api/v1/ limit=100
    INFO:swh.core.config:Loading config file /etc/softwareheritage/scheduler.yml
    Created 1 tasks

      Interval: 90 days, 0:00:00
      Type: list-gitea-full

+Register task types to the scheduler
+------------------------------------
+
+- To register new task types, ensure you have the code at the required version:
+
+  - docker environment: use :file:`docker-compose.override.yml` with the desired
+    :ref:`volume for both lister and scheduler* containers<run-lister-tutorial>`
+  - for production/staging, upgrade the swh package first then trigger the cli.
+
+- Use the ``swh scheduler task-type register`` command:
+
+::
+
+   $ swh scheduler --config-file /etc/softwareheritage/scheduler.yml task-type register
+   INFO:swh.core.config:Loading config file /etc/softwareheritage/scheduler.yml
+   INFO:swh.scheduler.cli.task_type:Loading entrypoint for plugin lister.launchpad
+   INFO:swh.scheduler.cli.task_type:Create task type list-launchpad-incremental in scheduler
+   INFO:swh.scheduler.cli.task_type:Create task type list-launchpad-full in scheduler
+   INFO:swh.scheduler.cli.task_type:Create task type list-launchpad-new in scheduler
+   ...
+
+
+Note: The command is idempotent so it can be executed multiple times.
