 - This component internally uses [FeatureToggleServiceComponent](https://www.npmjs.com/package/@sourceloop/feature-toggle-service) that requires a datasource binding with the name 'FeatureToggleDB'. Make sure to create a datasource for it.

 - This endpoint would onboard the tenant in the DB, and its success you should trigger the relevant events using the `/tenants/{id}/provision` endpoint.
 - The provisioning endpoint will invoke the publish method on the `EventConnector`. This connector's purpose is to provide a place for consumer to write the event publishing logic. And your custom service can be bound to the key `EventConnectorBinding` exported by the service.
 
+## Direct Tenant Onboarding
+
+In addition to the lead-based onboarding flow, a new tenant can also be onboarded directly without creating a lead first.
+This capability is designed specifically for control plane administrators, who can create and provision tenants directly through the management APIs.
+
+To ensure security and operational control, only users with control plane admin privileges are allowed to perform direct tenant onboarding.
+Regular users or leads cannot bypass the standard lead creation and verification process.
 ## Event Publishing
 
 The service supports pluggable event strategies — EventBridge, SQS, and BullMQ — through the loopback4-message-bus-connector.

+### Keycloak IdP Provider
+
+The Keycloak IdP Provider automatically sets up and configures all the required Keycloak resources for a new tenant during onboarding.
+
+It eliminates manual setup and ensures each tenant has a secure, isolated identity environment.
+
+When a new tenant is provisioned, the provider automatically:
+- Creates a Realm in Keycloak for that tenant.
+(Each tenant gets its own isolated authentication space.)
+
+- Configures SMTP (Email) settings in the realm using AWS SES for password reset and notification emails.
+
+- Creates a Client inside the realm for the tenant’s application with the correct redirect URIs and credentials.
+
+- Creates an Admin User for the tenant with a temporary password and triggers a password reset email.
+
+- Returns the admin user’s ID (authId) after successful setup.
+
+This setup ensures that every tenant has a ready-to-use Keycloak environment, complete with its own realm, client, and admin user, enabling secure login and user management from day one.
