-You can find more information in the wiki.
+### Backend of MySU is divided into several components:
+- **Buddy** is **deprecated** and has no use for the application, as of now.
+- **Calendar** is responsible for handling events provided by different associations. It contains information about: enrollment and enrollment options, event types, and events themselves.
+- **Email** is responsible for distributing emails to members of the various associations. 
+- **Exams** is **deprecated** and has no use for the application, as of now.
+- **Financial** is responsible for handling the finances of the associations and their particular members. Contains information about: bank accounts, debt entries, debt collections and invoices.
+- **Inventory** is **deprecated** and has no use for the application, as of now.
+- **MySU [API]** is responsible for handling the requests and responses between the frontend and backend.
+- **MySU [Backend]** is a main part of the code that the other components are built upon. It handles all the major work and provides the functionality for the web application.
