 The plugin is available as a pre-bundled Docker image.
 This image includes Keycloak and the plugin enabled for basic use cases.
-For more complex setup, the JAR file published in the Maven repository should be used to build a custom Keycloak image.

+### Customized Keycloak plugin image
 
 In many cases, Keycloak customization is necessary for branding or to meet custom
 authentication and authorization requirements. The default plugin image can be used
 in conjunction with docker multi-stage builds to extract the Keycloak plugin JARs and
 create a customized Keycloak image.

 Extends Keycloak for integration with Identus cloud agent in [OID4VCI](https://openid.net/specs/openid-4-verifiable-credential-issuance-1_0.html) flow.
 The Keycloak instance to use this is the Issuer Authorization Server where the plugin takes care of
 the OpenID extension in the issuance flow.
 The plugin supports the Authorization Endpoint and Token Endpoint according to the specification.
 Additionally, the plugin communicates with the cloud agent during holder authorization to coordinate the issuance session.
