 To run many parallel materialization jobs, you'll want to use the **SQL registry** (which is already used in this module).
 Then you could run multiple materialization jobs in parallel (e.g. using `feast materialize [FEATURE_VIEW_NAME] start_time end_time`) 
 
-### Step 7a: Scheduling materialization
+### Step 7: Scheduling materialization
 To ensure fresh features, you'll want to schedule materialization jobs regularly. This can be as simple as having a cron job that calls `feast materialize-incremental`. 
 
 Users may also be interested in integrating with Airflow, in which case you can build a custom Airflow image with the Feast SDK installed, and then use a `PythonOperator` (with `store.materialize`).
 
+#### Step 7a: Setting up Airflow
+
 We setup a standalone version of Airflow to set up the PythonOperator (Airflow now prefers @task for this). 
 
 ```bash
