+<Expandable title="In what environments should I enable the Dev Toolbar?">
+
+Since the Dev Toolbar will be visible to users within your app, it's important to consider which environments should render it.
+
+If your web application does require authentication to access:
+- In dev and staging, always initialized the Dev Toolbar.
+- In production conditionally initialize the Dev Toolbar when an employee is logged in.
+
+If you web application does not require authenticaion:
+- In dev and staging environments initialize the Toolbar at all times.
+- In production environments, do not initialize the Toolbar.
+
+Initializing the Dev Toolbar allows all developers and testers can use it and quickly go from the page they're looking at back to Sentry for further debugging.
+In production it can make it easier for developers to reproduce issues, but it should not be initialized for all users of the site -- only when an employee/engineer/etc visits.
+
+Once you decide where and when you want the Toolbar to appear, you'll write those conditions into your codebase. The specific implementation is something you'll need to write based on how your app works and how your dev team is set up.

+Implementing the specific conditions for initializing the Toolbar will vary from app to app and which ever framework or template library is in use.

   - The setup and deploy instruction are very different. The SDK is best deployed on staging and production environments, and can be configured easily with environment variables. The Dev Toolbar requires special considerations to deploy it into production, usually by creating a condition so that it's only included for members of your own Sentry organization.

-If the toolbar `<script>` is included on your site, and `SentryToolbar.init()` is called, then a "Login to Sentry" button will be visible to the public. This is not ideal, but your data in Sentry will still be safe as users outside of your Sentry organization will not be able to login.
 
+See the [FAQ: _"How can I conditionally initialize the Toolbar?"_](/product/dev-toolbar/faq/) for help implementing conditions for different environments.
 
 ### Init Configuration Options
 
-At minimum, you should be calling `.init()` with these two options:
-```javascript
-window.SentryToolbar.init({
-  organizationSlug: 'acme',
-  projectIdOrSlug: 'website',
-});
-```
+At minimum, you must set `organizationSlug` and `projectIdOrSlug`.
 
-And you can also include any additional options from this list:
+The complete list of options is here:
 
 | Option | Type | Description | Default Value |
-| ----- | ----- | ----- | ----- |
+| ------ | ---- | ----------- | ------------- |
 | `organizationSlug` | `string` | The organization that users should login to. For example \'acme\' | *Required Value* |
 | `projectIdOrSlug` | `string \| number` | The project for which this website/webapp is associated. | *Required Value* |
 | `environment (optional)` | `string \| string[] \| undefined` | The environment of this deployment. Used to narrow search results in the Toolbar UI. Set to `undefined` or `""` or `[]` if you want to see results from all environments. | `undefined` |
@@ -111,15 +98,53 @@ And you can also include any additional options from this list:
 | `debug (optional)` | `string \| undefined` | A comma separated string of debug targets to enable. Example: `'logging,state'`. If the list contains 'all' or 'true' then all targets will be enabled. Valid targets: `'logging' 'login-success' 'settings' 'state'` | `undefined` |
 | `mountPoint (optional)` | `HTMLElement \| () => HTMLElement \| undefined` | Where to mount the Toolbar in the DOM. | `document.body` |

+The React hook supports some other top-level options. The defaults values are:

+| `enabled` | `booleand (optional)` | Conditionally initialize the toolbar. Set this to false to avoid requesting the toolbar code on the browser, or to safely unmount an existing toolbar instance | `true` |
+| `version` | `string (optional)` | Request a speicifc version of the toolbar from the CDN. It's recommended to use `latest` for automatic updates. See https://github.com/getsentry/sentry-toolbar/releases for a list of available release tags. | `'latest'` |
+| `cdn` | `string (optional)` | Overrides the `version` field above. Setting the CDN is useful if you want to self-host a specific version of the Toolbar. | `'https://browser.sentry-cdn.com/sentry-toolbar/latest/toolbar.min.js'` |
+
+
 ### Unmounting the Toolbar
 
 If you have called `SentryToolbar.init({...})` to render the Toolbar, but now want to manually remove or unmount it from the page, you can call the cleanup function that is returned from `init()`. This will unmount all the injected HTML and CSS. Login credentials will not be removed, so you can re-insert the toolbar and still be authenticated.
+
+If you are using the React hook, then the toolbar will unmount when the react component is unmounted. Or if you set `enabled: false`.
+
 ```javascript
 const unmountToolbar = window.SentryToolbar.init({ ... });
 
 // sometime later...
 unmountToolbar();
 ```
+```javascript {tabTitle:React}
+useSentryToolbar({
+  enabled: false, // The toolbar will not be mounted
+  initProps: {
+    ...
+  },
+})
+```
