 Note that gateway-specific variables take precedence over global ones. In the example above, the `gw_var` used in a model will resolve to the value specified in the model's gateway.
 
 For further customization, you can also enable [gateway-specific model defaults](../guides/configuration.md#gateway-specific-model-defaults). This allows you to define custom behaviors, such as specifying a dialect with case-insensitivity normalization.
 
-The default gateway is `redshift` In the example configuration above, so all models without a `gateway` specification will run on redshift, as in this `order_dates` model:
