+## Setting Configuration via Environment Variables
+
+Inertia Rails supports setting any configuration option via environment variables out of the box. For each option in the configuration, you can set an environment variable prefixed with `INERTIA_` and the option name in uppercase. For example: `INERTIA_SSR_ENABLED`.
+
+**Boolean values** (like `INERTIA_DEEP_MERGE_SHARED_DATA` or `INERTIA_SSR_ENABLED`) are parsed from the strings `"true"` or `"false"` (case-sensitive).
+
 ## Configuration Options
 
 ### `component_path_resolver`
 
-Use `component_path_resolver` to customize component path resolution when [`default_render`](#default_render) config value is set to `true`. The value should be callable and will receive the `path` and `action` parameters, returning a string component path. See [Automatically determine component name](/guide/responses#automatically-determine-component-name).
-
 **Default**: `->(path:, action:) { "#{path}/#{action}" }`

+
 ### `deep_merge_shared_data`
 
+**Default**: `false`  
+**ENV**: `INERTIA_DEEP_MERGE_SHARED_DATA`
+
 When enabled, props will be deep merged with shared data, combining hashes
 with the same keys instead of replacing them.
 
-**Default**: `false`
-
 ### `default_render`
 
-Overrides Rails default rendering behavior to render using Inertia by default.
+**Default**: `false`  
+**ENV**: `INERTIA_DEFAULT_RENDER`
 
-**Default**: `false`
+Overrides Rails default rendering behavior to render using Inertia by default.
 
 ### `encrypt_history`
 
+**Default**: `false`  
+**ENV**: `INERTIA_ENCRYPT_HISTORY`
+
 When enabled, you instruct Inertia to encrypt your app's history, it uses
 the browser's built-in [`crypto` api](https://developer.mozilla.org/en-US/docs/Web/API/Crypto)
 to encrypt the current page's data before pushing it to the history state.
 
-**Default**: `false`
-
 ### `ssr_enabled` _(experimental)_
 
+**Default**: `false`  
+**ENV**: `INERTIA_SSR_ENABLED`
+
 Whether to use a JavaScript server to pre-render your JavaScript pages,
 allowing your visitors to receive fully rendered HTML when they first visit
 your application.
 
 Requires a JS server to be available at `ssr_url`. [_Example_](https://github.com/ElMassimo/inertia-rails-ssr-template)
 
-**Default**: `false`
-
 ### `ssr_url` _(experimental)_
 
+**Default**: `"http://localhost:13714"`
+**ENV**: `INERTIA_SSR_URL`
+
 The URL of the JS server that will pre-render the app using the specified
 component and props.
 
-**Default**: `"http://localhost:13714"`
-
 ### `version` _(recommended)_
 
+**Default**: `nil`
+**ENV**: `INERTIA_VERSION`
+
 This allows Inertia to detect if the app running in the client is oudated,
 forcing a full page visit instead of an XHR visit on the next request.

-**Default**: `nil`
+### `parent_controller`
+
+**Default**: `'::ApplicationController'`
+**ENV**: `INERTIA_PARENT_CONTROLLER`
+
+Specifies the base controller class for the internal `StaticController` used to render [Shorthand routes](/guide/routing#shorthand-routes).
+
+By default, Inertia Rails creates a `StaticController` that inherits from `ApplicationController`. You can use this option to specify a different base controller (for example, to include custom authentication, layout, or before actions).
