+= CAS Login & Logout Sample
+
+This guide provides instructions on setting up an application that uses the CAS protocol for login.
+It uses https://casserver.herokuapp.com/cas/login as the server supporting the CAS protocol.
+
+The sample application uses Spring Boot and the `spring-security-cas`.
+
+== Goals
+
+=== CAS Login
+
+`cas/login` provides a very simple implementation of a CAS Service (application) that use a public test CAS server for
+ authentication.
+
+The following features are implemented in the MVP:
+
+1. Login
+2. Logout
+
+== Run the Sample
+
+=== Start up the Sample Application in Tomcat with Gretty
+[source,bash]
+----
+ ./gradlew :servlet:java-configuration:cas:login:appRun
+----
+
+=== Open a Browser
+
+https://localhost:8443/
+
+You will be redirect to a sample CAS server: https://casserver.herokuapp.com/cas
+
+=== Type in the credentials
+
+[source,bash]
+----
+User: casuser
+Password: Mellon
+----
+
+=== Run a local CAS server
+Run the following script to install and start a CAS server that responds at http://localhost:8090/cas/login
+
+[source,bash]
+----
+servlet/java-configuration/cas/install-cas/install-cas.sh
+----
+or with Docker:
+[source,bash]
+----
+servlet/java-configuration/cas/install-cas/run-cas-docker.sh
+----
+
+Adjust the `servlet/java-configuration/cas/login/src/main/resources/security.properties` file to point at local CAS server:
+
+[source,bash]
+----
+cas.base.url=http://localhost:8090/cas
+cas.login.url=http://localhost:8090/cas/login
+----
+
+Then run the CAS login app in gretty and browse to https://localhost:8443.
+
+[source,bash]
+----
+ ./gradlew :servlet:java-configuration:cas:login:appRun
+----
