+# 🔧 Instalacja Node.js na Fedora Atomic
+
+## Problem
+Na Fedora Atomic nie ma prostej opcji `dnf install nodejs` ze względu na niezmienność systemu. Trzeba użyć **toolbox** lub alternatywnych sposobów.
+
+## Rozwiązanie 1: Toolbox (Rekomendowane)
+
+Toolbox tworzy kontener z pełnym dostępem do pakietów.
+
+```bash
+# Krok 1: Stwórz nowy toolbox kontener
+toolbox create
+
+# Krok 2: Wejdź do kontenera
+toolbox enter
+
+# Krok 3: Zainstaluj Node.js i npm
+sudo dnf install nodejs npm -y
+
+# Krok 4: Wyjdź z kontenera
+exit
+
+# Krok 5: Sprawdź instalację (powinno działać z poziomu hosta)
+node --version
+npm --version
+```
+
+## Rozwiązanie 2: Homebrew
+
+Homebrew działa natywnie na Fedora Atomic.
+
+```bash
+# Krok 1: Zainstaluj Homebrew (jeśli nie masz)
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+
+# Krok 2: Dodaj do PATH (jeśli nie dodano automatycznie)
+echo 'eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"' >> ~/.bashrc
+source ~/.bashrc
+
+# Krok 3: Zainstaluj Node.js
+brew install node
+
+# Krok 4: Sprawdź
+node --version
+npm --version
+```
+
+## Rozwiązanie 3: NVM (Node Version Manager)
+
+NVM pozwala na installowanie wielu wersji Node.js.
+
+```bash
+# Krok 1: Zainstaluj NVM
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+
+# Krok 2: Załaduj NVM
+source ~/.bashrc
+
+# Krok 3: Zainstaluj Node.js
+nvm install node
+
+# Krok 4: Sprawdź
+node --version
+npm --version
+```
+
+## Rozwiązanie 4: Pobrać prebuilt (Szybko)
+
+```bash
+# Pobierz Node.js
+cd ~/Downloads
+wget https://nodejs.org/dist/v20.10.0/node-v20.10.0-linux-x64.tar.xz
+
+# Rozpakuj
+tar -xf node-v20.10.0-linux-x64.tar.xz
+
+# Dodaj do PATH
+export PATH="$HOME/Downloads/node-v20.10.0-linux-x64/bin:$PATH"
+
+# Dodaj na stałe do .bashrc aby zachowało się między restartami
+echo 'export PATH="$HOME/Downloads/node-v20.10.0-linux-x64/bin:$PATH"' >> ~/.bashrc
+source ~/.bashrc
+
+# Sprawdź
+node --version
+npm --version
+```
+
+---
+
+## Po instalacji Node.js
+
+### Uruchom frontend:
+```bash
+cd frontend
+npm install      # Zainstaluj zależności (tylko raz)
+npm start        # Uruchom aplikację
+```
+
+### Lub uruchom całą aplikację:
+```bash
+python main.py
+# Wybierz opcję 1 (uruchomić tylko backend) lub q (zainstalować Node.js)
+```
+
+---
+
+## Diagnostyka jeśli coś nie działa
+
+```bash
+# Sprawdź gdzie jest node
+which node
+which npm
+
+# Sprawdź wersje
+node --version
+npm --version
+
+# Uwaga: Jeśli Node.js zainstalowany w toolbox, mogą być dostępne tylko w toolbox
+# Użyj wtedy:
+toolbox run node --version
+toolbox run npm --version
+```
+
+## Najszybsze rozwiązanie dla Fedora Atomic:
+
+```bash
+# Terminal 1 - Backend
+python main.py  # wybiez opcja 1
+
+# Terminal 2 - Frontend (jeśli Node zainstalowany)
+cd frontend && npm install && npm start
+
+# Lub jeśli Node w toolbox:
+# Terminal 2
+toolbox run bash -c 'cd /var/home/krzysztof/Documents/inz/git_fix/frontend && npm install && npm start'
+```
+
+---
+
+**Osobiście polecam Rozwiązanie 1 (Toolbox)** - najprościej i najczystsze dla Fedora Atomic.

+
+## 🚀 Szybki start
+
+### Uruchomienie całej aplikacji (jedno polecenie)
+
+```bash
+python launcher.py
+```
+
+To uruchomi:
+- ✅ Backend FastAPI (port 8000)
+- ✅ Frontend React (port 3000)
+- ✅ Otworzy przeglądarkę na http://localhost:3000
+
+### Ręczne uruchomienie poszczególnych części
+
+**Backend:**
+```bash
+cd backend/app
+python main.py
+```
+
+**Frontend:**
+```bash
+cd frontend
+npm install
+npm start
+```
+
+## 📡 API Endpoints
+
+### 1. Inicjalizacja systemu
+```http
+POST /api/init
+Content-Type: application/json
+
+{
+  "password": "twoje_bezpieczne_haslo_8znaków_min"
+}
+```
+
+**Response:**
+```json
+{
+  "status": "success",
+  "recovery_key": "a1b2c3d4e5f6...",
+  "message": "System initialized. Save recovery key in safe place."
+}
+```
+
+### 2. Logowanie - hasłem głównym
+```http
+POST /api/login
+Content-Type: application/json
+
+{
+  "password": "twoje_haslo",
+  "is_recovery": false
+}
+```
+
+**Response:**
+```json
+{
+  "status": "success",
+  "message": "Successfully authenticated"
+}
+```
+
+### 3. Logowanie - kluczem awaryjnym
+```http
+POST /api/login
+Content-Type: application/json
+
+{
+  "password": "a1b2c3d4e5f6...",
+  "is_recovery": true
+}
+```
+
+**Response:**
+```json
+{
+  "status": "success",
+  "message": "Authenticated with recovery key. Please change password."
+}
+```
+
+### 4. Sprawdzenie statusu
+```http
+GET /api/status
+```
+
+**Response:**
+```json
+{
+  "is_initialized": true
+}
+```
+
+## 🔐 Bezpieczeństwo
+
+### Zaimplementowane zabezpieczenia:
+- ✅ **Hashing haseł** - Argon2 (type="ID")
+- ✅ **Losowe klucze awaryjne** - 32 znaki hex
+- ✅ **CORS** - ograniczony do zaufanych domen
+- ✅ **Walidacja danych** - Pydantic
+- ✅ **Dwie ścieżki dostępu** - hasło główne + klucz awaryjny
+
+### Zmienne środowiskowe (.env)
+```bash
+ENVIRONMENT=development           # development | production
+DATABASE_PATH=archivium.db       # lokalizacja bazy
+ALLOWED_ORIGINS=http://localhost:3000,http://localhost:5173
+```
+
+### Rekomendacje produkcyjne:
+1. Użyj **PostgreSQL** zamiast SQLite
+2. Włącz **HTTPS/SSL**
+3. Dodaj **rate limiting**
+4. Włącz **logging i monitoring**
+5. Regularne **backupy** bazy danych
+6. Przechowuj sekrety w zmiennych środowiskowych
+
+## 📚 Szczegółowa dokumentacja struktury
+
+### Backend - Endpointy (src/routers/)
+
+**init.py** - `POST /api/init`
+- Inicjalizuje system
+- Generuje recovery key (32 znaki)
+- Hashuje hasło główne z Argon2
+
+**login.py** - `POST /api/login`
+- Logowanie hasłem głównym lub kluczem awaryjnym
+- Weryfikuje hash haseł
+- Zwraca status autoryzacji
+
+**status.py** - `GET /api/status`
+- Sprawdza czy system zainicjalizowany
+- Zwraca boolean `is_initialized`
+
+### Backend - Core modules (src/)
+
+**config.py** - Konfiguracja
+- CORS configuration
+- DATABASE_PATH z zmiennych środowiskowych
+- ALLOWED_ORIGINS
+
+**models.py** - SQLAlchemy ORM
+- SecurityConfig model
+- Tabela `security_config`
+- Przechowuje hashe haseł i kluczy
+
+**schemas.py** - Pydantic validation
+- InitRequest - walidacja do /api/init
+- LoginRequest - walidacja do /api/login
+
+**database.py** - Zarządzanie bazą
+- SQLite setup
+- Session management
+- `init_db()` - inicjalizuje schemat
+- `get_db()` - dependency injection dla sessionów
+
+**security.py** - Funkcje bezpieczeństwa
+- `hash_password(password: str) -> str`
+- `verify_password(password: str, hash_value: str) -> bool`
+- `generate_recovery_key() -> str`
+
+**main.py** - FastAPI aplikacja (35 linii!)
+- Konfiguracja CORS middleware
+- Include routery
+- Startup event dla init_db()
+
+## 🛠️ Development
+
+### Instalacja dependencies
+
+```bash
+# Backend
+pip install -r requirements.txt
+
+# Lub z uv:
+cd backend/app && uv sync
+
+# Frontend
+cd frontend && npm install
+```
+
+### Testowanie API
+
+```bash
+# Curl - Inicjalizacja
+curl -X POST http://localhost:8000/api/init \
+  -H "Content-Type: application/json" \
+  -d '{"password": "TestPassword123"}'
+
+# Curl - Logowanie
+curl -X POST http://localhost:8000/api/login \
+  -H "Content-Type: application/json" \
+  -d '{"password": "TestPassword123", "is_recovery": false}'
+
+# Status
+curl http://localhost:8000/api/status
+```
+
+### Dokumentacja interaktywna
+
+Gdy serwer działa, otwórz: **http://localhost:8000/docs**
+- Swagger UI do testowania API
+- Automatyczna dokumentacja OpenAPI
+- Try it out - testuj bezpośrednio z przeglądarki
+
+## 📝 Historia zmian
+
+Pełna historia zmian w [CHANGELOG.md](CHANGELOG.md)
+
+### v0.1.1 - Monorepo Integration
+- Reorganizacja całego projektu do struktury monorepo
+- Backend w `backend/app/` (35 linii main.py!)
+- Launcher do uruchamiania całej aplikacji
+- Integracja z starym kodem z `Database/` i `TextEditor/`
+- Kompletna dokumentacja
+
+### v0.1.0 - Refactorization
+- Refaktoryzacja kodu, usunięcie komentarzy
+- Modularyzacja na src/
+- Bezpieczeństwo (CORS, Argon2, walidacja)
+
+## 🐛 Troubleshooting
+
+### Problem: Port 8000 już w użyciu
+```bash
+# Zmień w backend/app/main.py lub użyj:
+cd backend/app && uv run uvicorn main:app --port 8001
+```
+
+### Problem: Frontend nie łączy się z backendem
+Sprawdź w `backend/app/src/config.py`:
+```python
+ALLOWED_ORIGINS = ["http://localhost:3000"]
+```
+
+### Problem: Baza danych uszkodzona
+```bash
+rm archivium.db        # Usuń stary plik
+python launcher.py     # Przeinicjalizuj
+```
+
+### Problem: npm start nie działa
+```bash
+cd frontend
+rm -rf node_modules package-lock.json
+npm install
+npm start
+```
+
