+# Development Setup - LLM Monitor
+
+## 🛠️ Setup Locale
+
+### 1. Installare Dipendenze Python
+
+```bash
+python3 -m venv venv
+source venv/bin/activate  # Windows: venv\Scripts\activate
+pip install -r requirements.txt
+pip install -r requirements-dev.txt
+```
+
+### 2. Installare Dipendenze Node (per Tailwind CSS)
+
+```bash
+npm install
+```
+
+### 3. Compilare Tailwind CSS
+
+#### Modalità Development (watch mode)
+```bash
+npm run tailwind:dev
+```
+
+Questo comando:
+- Compila `app/web/static/css/input.css` in `app/web/static/css/output.css`
+- Rimane in watch mode per compilare automaticamente al salvataggio
+- Legge la configurazione da `tailwind.config.js`
+
+#### Modalità Production (minified)
+```bash
+npm run tailwind:build
+```
+
+Questo comando:
+- Compila e minifica il CSS
+- Ottimizzato per produzione
+- Usato durante il build Docker
+
+### 4. Avviare l'Applicazione
+
+In una finestra di terminale (con `npm run tailwind:dev` in watch):
+
+```bash
+source venv/bin/activate
+python3 -m uvicorn main:app --reload --host 0.0.0.0 --port 8000
+```
+
+O usar il comando Makefile:
+```bash
+make dev
+```
+
+Accedi a: http://localhost:8000
+
+---
+
+## 📱 Workflow di Sviluppo
+
+### Sviluppare il Frontend
+
+1. **Terminal 1 - Tailwind Watcher:**
+   ```bash
+   npm run tailwind:dev
+   ```
+
+2. **Terminal 2 - FastAPI Dev Server:**
+   ```bash
+   source venv/bin/activate
+   uvicorn main:app --reload
+   ```
+
+3. **Modificare i file:**
+   - HTML: `app/web/templates/index.html`
+   - CSS input: `app/web/static/css/input.css` (raramente, usa classi Tailwind)
+   - JavaScript: `app/web/static/js/app.js` e `data-sync.worker.js`
+
+4. **Compilato automaticamente:**
+   - Tailwind genera `app/web/static/css/output.css` automaticamente
+   - FastAPI recarica il server automaticamente
+   - Browser reload automatico (se abilitato)
+
+---
+
+## 🐳 Build Docker
+
+Il Dockerfile multi-stage:
+
+1. **Stage 1 - CSS Builder (Node):**
+   - Installa dipendenze npm
+   - Compila Tailwind CSS
+   - Genera `app/web/static/css/output.css`
+
+2. **Stage 2 - Python Builder:**
+   - Installa dipendenze Python
+   - Crea virtualenv
+
+3. **Stage 3 - Runtime:**
+   - Copia CSS compilato dal Stage 1
+   - Copia Python packages dal Stage 2
+   - Immagine finale ottimizzata (~300MB)
+
+### Build locale:
+```bash
+docker build -t llm-monitor:latest .
+```
+
+### Eseguire il container:
+```bash
+docker run -p 8000:8000 --env-file .env llm-monitor:latest
+```
+
+---
+
+## ⚙️ Configurazione Tailwind
+
+File: `tailwind.config.js`
+
+```javascript
+module.exports = {
+  content: [
+    "./app/web/templates/**/*.html",
+    "./app/web/static/**/*.js",
+  ],
+  theme: {
+    extend: {},
+  },
+  plugins: [],
+}
+```
+
+**Content**: Specifica quali file Tailwind deve scansionare per le classi utilizzate
+
+---
+
+## 🎯 CSS Architecture
+
+### Input CSS
+File: `app/web/static/css/input.css`
+```css
+@tailwind base;
+@tailwind components;
+@tailwind utilities;
+```
+
+### Output CSS
+File: `app/web/static/css/output.css` (generato)
+- Contiene solo le classi Tailwind utilizzate
+- Minificato in produzione (~30KB)
+- Ottimizzato per performance
+
+### Usage in HTML
+File: `app/web/templates/index.html`
+```html
+<!-- Usa il CSS compilato (produzione) -->
+<link rel="stylesheet" href="/static/css/output.css">
+
+<!-- Fallback CDN per sviluppo (se output.css non esiste) -->
+<script src="https://cdn.tailwindcss.com"></script>
+```
+
+---
+
+## 📝 Tips di Sviluppo
+
+### Hot Reload CSS
+```bash
+npm run tailwind:dev
+# Guarda i file e compila automaticamente
+```
+
+### Debug CSS Compilation
+```bash
+npm run tailwind:build
+# Se il CSS non appare, verifica:
+# 1. Le classi sono usate nei file HTML/JS?
+# 2. C'è un errore nella sintassi CSS?
+# 3. I percorsi in tailwind.config.js sono corretti?
+```
+
+### Aggiungere Nuove Classi Tailwind
+1. Modifica i file HTML/JS con classi Tailwind
+2. Tailwind watcher le detetta automaticamente
+3. `output.css` viene rigenerato
+
+```html
+<!-- Nuova classe aggiunta -->
+<div class="bg-gradient-to-r from-purple-500 to-pink-500">
+  <!-- Viene aggiunta automaticamente al CSS compilato -->
+</div>
+```
+
+---
+
+## 🚀 Production Checklist
+
+- [ ] Eseguire `npm run tailwind:build` per minificare
+- [ ] Verificare che `output.css` sia generato
+- [ ] Controllare che il container Docker usi il CSS compilato
+- [ ] Test performance con Lighthouse
+- [ ] Verifica bundle size `output.css`
+
+---
