+## Public client configuration
+
+[Home Assistant](https://github.com/home-assistant/core) `/var/lib/hass/configuration.yaml`
+
+```yaml
+auth_oidc:
+  client_id: "homeassistant"
+  discovery_url: "https://idm.example.org/oauth2/openid/homeassistant/.well-known/openid-configuration"
+  features:
+    automatic_person_creation: true

+
+1. Create your Kanidm account, if you don't have one already:
+
+```shell
+kanidm person create "your_username" "Your Username" --name "idm_admin"
+```
+
+2. Create a new Kanidm group for your HomeAssistant administrators (`homeassistant_admins`), and add your regular account to it:
+
+```shell
+kanidm group create "homeassistant_admins" --name "idm_admin"
+kanidm group add-members "homeassistant_admins" "your_username" --name "idm_admin"
+```
+
+3. Create a new OAuth2 application configuration in Kanidm (`homeassistant`), configure the redirect URL, and scope access:
+
+```shell
+kanidm system oauth2 create-public "homeassistant" "Home Assistant" "https://hass.example.org/auth/oidc/welcome" --name "idm_admin"
+kanidm system oauth2 add-redirect-url "homeassistant" "https://hass.example.org/auth/oidc/callback" --name "idm_admin"
+kanidm system oauth2 update-scope-map "homeassistant" "homeassistant_users" "email" "groups" "openid" "profile" --name "idm_admin"
+```
