 ### config.vls
 
-_coming soon._
+VLS configuration accepts the same values that can be configured in VS code with keys that start with `vetur`. 
+These are configured with nested objects rather than dotted string notation. Typescript intellisense is available. 
 
-| field | Type | Default value | Description |
-| :---- | ---- | ------------- | ----------- |
-|       |      |               |             |
+See [`initParams.ts`](https://github.com/fi3ework/vite-plugin-checker/blob/8fc5d7f4a908a4c80d1cb978e0acf1d4e5700e6a/packages/vite-plugin-checker/src/checkers/vls/initParams.ts#L33) for a comprehensive list of the defaults that can be overridden. Vetur unfortunately does not provide a single comprehensive document of all its options.
+
+For example, to performing checking only the `<script>` block:
+```ts
+checker({
+  vls: {
+    vetur: {
+      validation: {
+        template: false,
+        templateProps: false,
+        interpolation: false,
+        style: false,
+      },
+    },
+  },
+}),
+```
