+## Projekt zaliczeniowy z laboratorium "Szkielety Programistyczne w Aplikacjach Internetowych"
+
+## Tematyka projektu: Aplikacja do przechowywania plików (File storage app)
+
+## Autor: Kacper Staroń
+
+## Funkcjonalności:
+- uwierzytelnianie
+- rejestracja
+- dodawanie plików
+- usuwanie plików, zmiana ich nazwy
+- zmiana danych logowania
+
+## Narzędzia i technologie:
+- strona serwera: Node.js + Express (web server) + Joi (walidacja) + Multer (middleware do obsługi uploadowania plików)
+- baza danych: MongoDB + Mongoose (silnik bazy danych)
+- strona klienta: Vite, Vue3, PrimeVue (komponenty)
+- konteneryzacja: Docker
+
+## Wymagania
+
+Wersje programów wykorzystane do tworzenia aplikacji (aplikacja nie została przetestowana z kompatybilnością wcześniejszych wersji):
+- MongoDB 6.0
+- Node.JS 20
+- Docker 28.2.2
+
+## Uruchomienie
+1. W folderze aplikacji należy uruchomić polecenie `docker compose up` aby zbudować i uruchomić kontenery aplikacji.
+2. Należy uruchomić `http://localhost:5173/`.
