 Configuring paramstyle
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Paramstyle can be set on both a module and cursor level. When paramstyle is set on a module level e.g. ``redshift_connector.paramstyle = 'qmark'``, the user specified paramstyle is used for all subsequent cursors unless set on the cursor.
-When paramstyle is set on the cursor e.g. ```cursor.paramstyle = 'qmark'`` the user specified paramstyle is only used for that cursor object.
+When paramstyle is set on the cursor e.g. ``cursor.paramstyle = 'qmark'`` the user specified paramstyle is only used for that cursor object.
