 To examine baseline image files, one might run `docker run --name=temp -it tier/grouper bash` and browse through these file system endpoints. While the container is running one may copy files out of the image/container using something like `docker cp containerId:/opt/grouper/grouper.api/conf/grouper.properties .`, which will copy the `grouper.properties` to the Docker client's present working directory. These files can then be edited and applied via the mechanisms outlined above.
 
+# Web Application Endpoints

+- `/grouper/`: location of the Grouper UI application
+- `grouper-ws/`: location of the Grouper WS application.
+- `/grouper-ws-scim/`: location of the Grouper SCIM Server application.

 Using standard methods, create a MariaDb Server and an empty Grouper database. Create a database user with privileges to create and populate schema objects. Set the appropriate database connection properties in `grouper.hibernate.properties`. Be sure to the user created with schema manipulation privileges as the db user.

 - [HTTP Strict Transport Security (HSTS)](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) is enabled on the Apache HTTP Server.
 - morphStrings functionality in Grouper is supported. It is recommended that the various morphString files be associated with the containers as Docker Secrets. Set the configuration file properties to use `/var/run/secrets/secretname`.
+- Grouper UI has been pre-configured to authenticate users via Shibboleth SP. 
+- By default, Grouper WS (hosted by `/opt/tomcat/`) and the Grouper SCIM Server (hosted by `/opt/tomee/`) use tomcat-users.xml for authentication, but by default no users are enabled. LDAP-backed authentication or other methods can be used and must be configured by the deployer.
