+### Password
+
+The password component behaves like `text`, but masks the input as the user types.

+
+const secret = await password({
+  message: 'Set a password.',
+  mask: '*',

 ### Select

+### Autocomplete
+
+The autocomplete component lets a user filter a list by typing, then choose one option from the matching results. By default, matching uses each option's `label`, `hint`, and `value`. The result is the selected option's `value`.
+
+```js
+import { autocomplete } from '@clack/prompts';
+
+const framework = await autocomplete({
+  message: 'Pick a framework.',
+  placeholder: 'Type to search...',
+  options: [

+    { value: 'sveltekit', label: 'SvelteKit' },
+    { value: 'remix', label: 'Remix' },
+  ],
+});
+```
+
+### Select Key
+
+The `selectKey` component lets a user choose an option by pressing its single-character string `value` key directly.
+
+```js
+import { selectKey } from '@clack/prompts';
+
+const action = await selectKey({
+  message: 'Pick an action.',
+  options: [
+    { value: 'd', label: 'Deploy' },

+    { value: 'q', label: 'Quit' },
+  ],
+});
+```

 ### Multi-Select
 
 The `multiselect` component allows a user to choose many values from a list of options. The result is an array with all selected `value` props.

+### Path
+
+The path component offers filesystem path suggestions and returns the selected path as a string. When `directory: true` is set, only directories can be selected.
+
+```js
+import { path } from '@clack/prompts';
+
+const targetDir = await path({
+  message: 'Select an existing directory.',
+  directory: true,

 ### Spinner
 
 The spinner component surfaces a pending action, such as a long-running download or dependency installation.
