-# Self Service Frontend
+# Self-Service Frontend
+
+The frontend of the new faculty-wide User Self-Service, FSI Self-Service (FSI = Fachschaften der Fakultät für Informatik)!
+
+The FSI Self-Service allows you to view and, partially, change some basic information about your FSI account, such as your name, major, and assigned groups.
+Notably, it also allows you to link your [Discord](https://fsi.rub.de/links/)-Account to your FSI account, granting you extended access to our Discord servers.
+
+It is planned to be available at [account.fsi.rub.de](https://account.fsi.rub.de/), but due to internal scheduling reasons, it unfortunately isn't live yet.  
+The backend is available [here](https://gitlab.ruhr-uni-bochum.de/fsi/idm/self-service-backend) (you may need to be logged in to view this link).
+
+## How it works
+
+- Single-page application powered by [React](https://react.dev/) and [TypeScript](https://www.typescriptlang.org/)
+- Styling using [Tailwind CSS](https://tailwindcss.com/)
+- [React Hook Form](https://react-hook-form.com/) for interative forms and input validation
+- Keeping track of state using [zustand](https://github.com/pmndrs/zustand)
+- Translation support using [FormatJS](https://formatjs.io/)
+- API Response validation using the slim [Valibot](https://valibot.dev/) library
+- [Vite](https://vitejs.dev/) as the build system, bundler, and tree-shaker 🌴
+- Code formatting and linting using [Prettier](https://prettier.io/) and [ESLint](https://eslint.org/)
+- Native [View Transitions](https://developer.mozilla.org/en-US/docs/Web/API/View_Transitions_API) thanks to [React Router](https://reactrouter.com/)
