-# backstage-plugin-auth-backend-module-guest-provider
+# Auth Module: Guest Provider
 
-The guest-provider backend module for the auth plugin.
+This module provides a guest auth provider implementation for `@backstage/plugin-auth-backend`. This is meant to supersede the existing `'guest'` option for authentication that does not emit tokens and is completely stored as frontend state.
 
-_This plugin was created through the Backstage CLI_
+**NOTE**:
+
+## Installation
+
+### Backend
+
+#### New Backend
+
+```diff
+const backend = createBackend();
+...
+
++backend.add(import('@backstage/plugin-auth-backend-module-guest-provider'));
+
+...
+backend.start();
+```
+
+#### Old Backend
+
+This module was also backported for the old backend and can be used like so,
+
+```diff
++import {
++  providers,
++} from '@backstage/plugin-auth-backend';
+    ....
+  return await createRouter({
+    ...
+    providerFactories: {
+        gitlab: providers.gitlab(),
++       guest: providers.guest(),
+        ...
+    }
+    ...
+```
+
+### Frontend
+
+Add the following to your `SignInPage` providers,
+
+```diff
++import {
++  guestAuthApiRef,
++} from '@backstage/core-plugin-api';
+
+const providers = [
++  {
++    id: 'guest-auth-provider',
++    title: 'Guest',
++    message: 'Sign in as a guest',
++    apiRef: guestAuthApiRef,
++  },
+   ...
+```
+
+### Config
+
+Similar to the other authentication providers, you have to enable the provider in config. Add the following to your `app-config.local.yaml`,
+
+```diff
+auth:
+    providers:
++       guest:
++           development: {}
+```
+
+We need to specify that the provider is enabled for the given environment, and as there are no config values for this provider yet, you can just specify an empty object.
