 # Projekt 2
+
+## Jak Rozpocząć?
+1. Pobierz repozytorium.
+2. Przejdź do głównego katalogu repozytorium.
+3. W terminalu wpisz `./start.sh`.
+4. Zostanie utworzony kontener Docker z bazą danych PostgreSQL, która zostanie zainicjalizowana danymi z pliku `init_db.sql`.
+5. Teraz można uruchomić plik `main.java`, który wykona operacje SELECT i INSERT na bazie danych.
