+**Scheduling queries**
+
+You can optionally allow your users to schedule queries directly in SQL Lab.
+This is done by addding extra metadata to saved queries, which are then picked
+up by an external scheduled (like [Apache
Airflow](https://airflow.apache.org/)).
+
+To allow scheduled queries, add the following to your `config.py`:
+
+.. code-block:: python
+
+ FEATURE_FLAGS = {
+ # Configuration for scheduling queries from SQL Lab. This information
is
+ # collected when the user clicks "Schedule query", and saved into the
`extra`
+ # field of saved queries.
+ # See: https://github.com/mozilla-services/react-jsonschema-form

+ 'JSONSCHEMA': {
+ 'title': 'Schedule',
+ 'description': (
+ 'In order to schedule a query, you need to specify when it
'
+ 'should start running, when it should stop running, and
how '
+ 'often it should run. You can also optionally specify '
+ 'dependencies that should be met before the query is '
+ 'executed. Please read the documentation for best
practices '
+ 'and more information on how to specify dependencies.'

+
+This feature flag is based on
[react-jsonschema-form](https://github.com/mozilla-services/react-jsonschema-form),
+and will add a button called "Schedule Query" to SQL Lab. When the button is
+clicked, a modal will show up where the user can add the metadata required for
+scheduling the query.
+
+This information can then be retrieved from the endpoint
`/savedqueryviewapi/api/read`
