+## Theming
+
+You can theme a prompt by passing a `theme` object option. The theme object only need to includes the keys you wish to modify, we'll fallback on the defaults for the rest.
+
+```ts
+type Theme = {
+  prefix: string | { idle: string; done: string };
+  spinner: {
+    interval: number;
+    frames: string[];
+  };
+  style: {
+    message: (text: string, status: 'idle' | 'done' | 'loading') => string;
+    error: (text: string) => string;
+    help: (text: string) => string;
+    key: (text: string) => string;
+  };
+  validationFailureMode: 'keep' | 'clear';
+};
+```
+
+`validationFailureMode` defines the behavior of the prompt when the value submitted is invalid. By default, we'll keep the value allowing the user to edit it. When the theme option is set to `clear`, we'll remove and reset to the default value or empty string.
