+## Validators
+
+There are two ways to configure validators. If you only want to add validators to your SDKs, set `sdk.validator` to a validator plugin name. This will implicitly add the selected plugin with default values.
+
+For a more granular approach, add a validator plugin and set `sdk.validator` to the plugin name or `true` to automatically select a plugin. Until you customize the validator plugin, both approaches will produce the same default output.
