+## CAS properties file
+
+Gazelle Transformation's CAS client is using a dedicated file in /opt/gazelle/cas which MUST be named "gazelle-transformation.properties".
+The properties file content must contain the following parameters :
+
+```
+casServerUrlPrefix=https://{FQDN}/sso
+casServerLoginUrl=https://{FQDN}/sso/login
+casLogoutUrl=https://{FQDN}/sso/logout
+service=https://{FQDN}/transformation
+```
+
+/!\ In the common file.properties, there is a serverName attribute which cannot be used at the same time with service, which explains why it is not 
+used anymore in this gazelle-transformation.properties file.
+
 ## Deploy the application
