 It's also possible to set the error value for a single input using `formState.setFieldError` and to clear a single input's value using `formState.clearField`.
 
+### Updating multiple fields at once
+
+Updating the value of multiple fields in the form at once is possible via the `formState.setFields` method.
+
+This could come in handy if you're, for example, loading data from the server.
+
+```js
+function Form() {
+  const [formState, { text, email }] = useFormState();
+
+  React.useEffect(function loadDataFromServer() {
+    // we'll simulate some delay with a setTimeout. This could be your fetch() request:
+    const timer = setTimeout(() => {
+      formState.setFields({
+        name: "John",
+        age: 24,
+        email: "john@example.com" 
+      });
+    },  1000);
+    return () => clearTimeout(timer);
+  }, []);
+
+  return (
+    <>
+      <input {...text('name')} readOnly />
+      <input {...text('age')} readOnly />
+      <input {...email('email')} readOnly />
+    </>
+  )
+}
+
+```
+
+`formState.setFields` has a second `options` argument which can be used to update the `touched`, `validity` and `errors` in the state.
+
+`touched` and `validity` can be a boolean value which applies that value to all fields for which a value is provided.
+
+```js
+// mark all fields as valid (clears all errors):
+formState.setFields(newValues, {
+  validity: true
+});
+
+// marks only "name" as invalid:
+formState.setFields(newValues, {
+  validity: {
+    name: false
+  },
+  errors: {
+    name: "Your name is required!"
+  }
+});
+
+// marks all fields as not touched:
+formState.setFields(newValues, {
+  touched: false
+});
+```
+
 ### Resetting The From State
 
 All fields in the form can be cleared all at once at any time using `formState.clear`.
