 For other changes beyond these images you will need to build a custom theme and identity-config image. Changes can be made to the [src/theme](https://github.com/defenseunicorns/uds-identity-config/tree/main/src/theme) directory. At this time only Account and Login themes are included, but email, admin, and welcome themes could be added as well.
 
+### Registration Form Fields
+
+Registration Form Fields, which by default are enabled, can be disabled to minimize the steps to register a new user. See [this section](https://uds.defenseunicorns.com/reference/uds-core/idam/customization/#templated-realm-values) for the example of disabling the registration form fields with the `themeCustomizations.settings.enableRegistrationFields` environment variable.
+
+When disabled, the following fields will not be present during registration:
+- Affiliation
+- Pay Grade
+- Unit, Organization or Company Name
+
 ### Testing Changes
 
 To test the `identity-config` theme changes, a local running Keycloak instance is required.
