 1. Make sure your **PostgreSQL** server is up and running and has a role with `CREATE` privilege for a target database, e.g.
 
     ```sql
-        my_database=> CREATE ROLE scheduler PASSWORD 'somestrong';
-        my_database=> GRANT CREATE ON DATABASE my_database TO scheduler;
+    my_database=> CREATE ROLE scheduler PASSWORD 'somestrong';
+    my_database=> GRANT CREATE ON DATABASE my_database TO scheduler;
     ```
 
 1. Create a new job, e.g. run `VACUUM` each night at 00:30
 
     ```sql
-        my_database=> SELECT timetable.add_job('frequent-vacuum', '30 0 * * *', 'VACUUM');
-        add_job
-        ---------
-            3
-        (1 row)
+    my_database=> SELECT timetable.add_job('frequent-vacuum', '30 0 * * *', 'VACUUM');
+    add_job
+    ---------
+        3
+    (1 row)
     ```
 
 1. Run the pg_timetable
 
     ```terminal
-        # pg_timetable postgresql://scheduler:somestrong@localhost/my_database --clientname=vacuumer
+    pg_timetable postgresql://scheduler:somestrong@localhost/my_database --clientname=vacuumer
     ```
