# Minecraft Launcher (Node.js + Electron) Funkcje: - Instalacja i uruchamianie Minecrafta z modami - Przeglądanie changelogów i aktualności - Społeczność (chat) - Zmiana wersji gry ## Uruchomienie 1. `npm install` 2. `npm start` ## Struktura - `main.js` — główny proces Electron - `preload.js` — most między rendererem a Node.js - `renderer/` — frontend (React) - `mods/` — folder na mody - `minecraft/` — folder gry ## Uwaga To jest szkielet launchera. Integracja z Minecraftem wymaga dodatkowych bibliotek (np.
