+"Scheduled actions do not run at the exact time they were expected"
+-------------------------------------------------------------------
+
+On the Odoo.sh platform, we cannot guarantee an exact running time for scheduled actions.
+
+This is due to the fact that there might be multiple customers on the same server, and we must guarantee a fair share of the server for every customer. Scheduled actions are therefore implemented slightly differently than on a regular Odoo server, and are run on a *best effort* policy.
+
+.. warning::
+    Do not expect any scheduled action to be run more often than every 5 min.
+
+Are there "best practices" regarding scheduled actions?
+-------------------------------------------------------
+
+**Odoo.sh always limits the execution time of scheduled actions (*aka* crons).**
+Therefore, you must keep this fact in mind when developing your own crons.
+
+We advise that:
+
+- Your scheduled actions should work on small batches of records.
+- Your scheduled actions should commit their work after processing each batch;
+  this way, if they get interrupted by the time-limit, there is no need to start over.
+- Your scheduled actions should be
+  `idempotent <https://stackoverflow.com/a/1077421/3332416>`_: they must not
+  cause side-effects if they are started more often than expected.

-Special worker
---------------
-
-On Odoo.sh, cron jobs and incoming mails are handled by a specific worker that is not accounted in
-the workers on your subscription. It is a kind of "hidden free worker" bound to every Odoo.sh
-instance.
-
-By default, this worker can spawn multiple concurrent threads to execute scheduled actions. The
-number of threads can be dynamically increased at runtime. However, its exact amount cannot be
-predicted as it varies according to the number of extra workers in the subscription, the current
-concurrency of incoming mails, the current server's load, etc.
-
-Limitations
------------
-
-- The delay between a scheduled task's next execution date and the actual triggering depends on many
-  parameters and can be delayed according to the state of the execution pool of the shared server.
-- Scheduled actions on staging branches are executed less often than production build.
-- The platform deactivates scheduled actions that repeatedly time out.
-- If the execution time of a scheduled action is business-critical, then we recommend using a
-  dedicated server as the scheduled actions timeout can be modified in the project settings.
-- We cannot guarantee an exact running time for scheduled actions on the Odoo.sh platform.

 If you're adding a repository that contains a lot of modules, you may want to ignore some of them in case there are any
 that are installed automatically. To do so, you can prefix your submodule folder with a :code:`.`. The platform will
 ignore this folder and you can hand pick your modules by creating symlinks to them from another folder.

-   This symlink has to be done within your GitHub repository. Do not try to create the symlink
