Installation prerequisites

LUY is a client/server application. On the client side, the application requires a web browser. On the server side, it requires a Java servlet engine, which provides the runtime environment for the application, plus a relational database in which the application data can be stored. This chapter describes the requirements on both the client as well as the server side.

We offer an on-premise installation version and a pre-prepared Docker image.
