## Overview

Outi-D is a JavaFX desktop learning and community client. Users sign in, then navigate courses and quizzes, participate in forums, or browse and reserve events; the UI also supports content export and event QR codes. The README describes REST/JWT access to a Symfony backend, while sampled services show direct JDBC through MyConnection, so both are represented without assuming a single data-access path. Several README capabilities are represented from documentation and the tree; their implementation wiring was not sampled.

Main entry points: [`src/main/java/services/EventService.java`](https://github.com/bohmide/outi-d-desktop/blob/main/src/main/java/services/EventService.java) (Event service), [`src/main/java/utils/MyConnection.java`](https://github.com/bohmide/outi-d-desktop/blob/main/src/main/java/utils/MyConnection.java) (JDBC connection), [`src/main/java/controllers/MainController.java`](https://github.com/bohmide/outi-d-desktop/blob/main/src/main/java/controllers/MainController.java) (Main navigation), [`src/main/java/controllers/ForumViewController.java`](https://github.com/bohmide/outi-d-desktop/blob/main/src/main/java/controllers/ForumViewController.java) (Forum screens)
