## Notes

Apereo CAS is the Java server of the CAS project, which handles sign-in for web applications. It is built on the Spring Framework and Spring Boot and speaks the CAS, SAML, OpenID Connect, OAuth 2.0 and WS-Federation protocols, and applications connect to it through the protocols they use. The [WAR overlay guide](https://apereo.github.io/cas/8.0.x/installation/WAR-Overlay-Installation.html) describes a Gradle project that builds a cas.war file for a servlet container such as Apache Tomcat, and the [Docker guide](https://apereo.github.io/cas/8.0.x/installation/Docker-Installation.html) offers images that are mostly meant as quickstarts and demos, plus a Helm chart for Kubernetes. The Apereo Foundation maintains the project.
