+## Git Workflow & Branching Strategy
+
+### Branching Model
+Проект використовує **Git Flow** стратегію з автоматизацією через GitHub Actions:
+
+```
+main/master     ←── Production releases (stable)
+    ↑
+develop         ←── Integration branch (beta releases)
+    ↑
+feature/*       ←── Feature development
+hotfix/*        ←── Urgent production fixes
+```
+
+### Branch Rules
+- **main/master**: Тільки стабільні релізи (v1.0.0, v1.1.0)
+- **develop**: Beta релізи для тестування (v1.1.0-beta.1)
+- **feature/**: Розробка нових функцій
+- **hotfix/**: Термінові виправлення для production
+
+### Workflow
+1. **Розробка**: `feature/auth-system` ← branch з develop
+2. **Code Review**: PR feature → develop
+3. **Integration**: PR develop → main (release готовий)
+4. **Hotfix**: `hotfix/critical-bug` ← branch з main
+
 ## CI/CD & Releases
 
+### GitHub Actions Workflows
+
+#### 1. **CI Pipeline** (`.github/workflows/ci.yml`)
+- **Triggers**: Push до develop, feature/*, hotfix/*
+- **Triggers**: PR до main, master, develop
+- **Actions**: Build, lint, type-check (без deploy)
+
+#### 2. **Release Pipeline** (`.github/workflows/release.yml`)
+- **Triggers**: Push до main, master, develop
+- **Actions**: Build + semantic-release + deploy
+- **Outputs**: 
+  - main → stable release (v1.0.0)
+  - develop → beta release (v1.1.0-beta.1)
+
+#### 3. **PR Validation** (`.github/workflows/pr-to-main.yml`)
+- **Triggers**: PR до main/master
+- **Actions**: Повна валідація перед merge
+
 ### Semantic Release
 Проект використовує [semantic-release](https://semantic-release.gitbook.io/) для автоматичних релізів:

+Тестове завдання: Fullstack Developer
+Завдання
+Реалізувати простий застосунок «Міні-блог з авторизацією».
+Функціонал
+    Фронтенд (Next.js + TypeScript):
+        Сторінка реєстрації / входу (email + пароль).
+        Сторінка зі списком постів (назва + короткий опис).
+        Сторінка одного поста (заголовок, текст, дата створення).
+        Сторінка створення нового поста (доступна тільки після авторизації).
+        Простий дизайн (Tailwind та будь-яку UI-бібліотеку).
+        -застосувати охайні базові стилі (TailwindCSS чи інша UI-бібліотека);
+        Сторінка редагування інформації про користувача (ім’я, email, пароль).
+
+Бекенд (Express.js + TypeScript):
+Авторизація (JWT або сесії):
+    POST /auth/register — реєстрація.
+    POST /auth/login — вхід.
+    
+    API для постів:
+    GET /posts — отримати всі пости.
+    GET /posts/:id — отримати конкретний пост.
+    POST /posts — створити новий пост (тільки авторизований користувач).
+    
+    API для користувачів:
+    GET /users/me — отримати інформацію про поточного авторизованого користувача.
+    PUT /users/me — оновити інформацію (ім’я, email, пароль).
+
+    (опціонально) DELETE /users/me — видалити свій акаунт.
+Зберігання даних:
+Використати PostgreSQL як базу даних.
+Роботу з БД реалізувати через Prisma.

+# Vercel Deployment Setup
+
+## 🚀 Deployment Steps
+
+### 1. Environment Variables
+
+Add these to your Vercel Dashboard (`Settings` → `Environment Variables`):
+
+```bash
+# Production Database
+DATABASE_URL="postgresql://user:password@host:5432/database?sslmode=require"
+
+# JWT Secret (generate strong secret)
+JWT_SECRET="your-super-secret-jwt-key-256-bit"
+
+# Node Environment
+NODE_ENV="production"
+
+# CORS Origins (your frontend domain)
+CORS_ORIGINS="https://your-project.vercel.app"
+```
+
+### 2. Database Options
+
+#### Option A: Vercel Postgres (Recommended)
+```bash
+# Install Vercel Postgres
+vercel storage create postgres
+
+# Copy connection string to env vars
+```
+
+#### Option B: Railway
+```bash
+# 1. Create account at railway.app
+# 2. Create PostgreSQL database
+# 3. Copy connection string
+```
+
+#### Option C: Supabase
+```bash
+# 1. Create project at supabase.com
+# 2. Go to Settings → Database
+# 3. Copy connection string
+```
+
+### 3. Deploy Commands
+
+```bash
+# Connect to Vercel
+vercel login
+
+# Link project
+vercel link
+
+# Deploy
+vercel --prod
+```
+
+### 4. After Deployment
+
+1. **Run migrations**:
+   ```bash
+   # In Vercel Functions tab, run:
+   npx prisma migrate deploy
+   ```
+
+2. **Test API**:
+   ```bash
+   curl https://your-project.vercel.app/api/health
+   ```
+
+## 🔧 Project Structure
+
+```
+├── vercel.json              # Vercel configuration
+├── .vercelignore           # Files to ignore
+├── backend/
+│   ├── api/index.ts        # Vercel Function entry
+│   ├── .env.production     # Production env template
+│   └── prisma/
+│       └── migrate-prod.ts # Production migrations
+└── frontend/               # Next.js app
+```
+
+## 📝 Manual Setup Steps
+
+1. **Create Vercel project**
+2. **Add environment variables** (see above)
+3. **Choose database provider**
+4. **Deploy**: `vercel --prod`
+5. **Run migrations** in Vercel dashboard
+6. **Test endpoints**
+
+## 🚨 Important Notes
+
+- **Never commit** real secrets to git
+- **Use strong JWT secret** (256-bit recommended)
+- **Enable SSL** for production database
+- **Set CORS origins** correctly
+- **Test thoroughly** before production use
