+description: Fully run the Grainlify project (Frontend + Backend + Database)
+---
+# Run Full Project
+
+This workflow sets up the database, configured the environment, and starts both backend and frontend servers.
+
+## 1. Environment Setup
+
+Ensure your local environment files are configured.
+
+```bash
+# Verify environment files exist (these should have been created/updated already)
+ls -la backend/.env frontend/.env
+```
+
+## 2. Database Setup
+
+We need to ensure the PostgreSQL container is running and correctly configured.
+
+### 2.1 Start PostgreSQL Container
+
+Check if `patchwork-postgres` exists. If not, create and start it.
+
+```bash
+// turbo
+# Check if container exists
+if ! docker ps -a --format '{{.Names}}' | grep -q "^patchwork-postgres$"; then
+    echo "Creating patchwork-postgres container..."
+    docker run --name patchwork-postgres -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:15
+else
+    echo "Container exists. Ensuring it is running..."
+    docker start patchwork-postgres
+fi
+```
+
+### 2.2 Configure Database Schema
+
+Run the setup script to create the database and user.
+
+```bash
+// turbo
+# Make executable just in case
+chmod +x backend/setup_grainlify_db.sh
+# Run setup script (might require sudo if docker needs it, but try without first given previous context)
+./backend/setup_grainlify_db.sh
+```
+
+## 3. Run Backend
+
+Start the Go backend server using the provided script.
+
+```bash
+cd backend
+# This script handles auto-reload with 'air' if available, or falls back to 'go run'
+./run-dev.sh
+```
+
+## 4. Run Frontend
+
+Start the React frontend in a separate terminal.
+
+```bash
+cd frontend
+pnpm run dev
+```
+
+## Verification
+
+- **Backend Health:** Visit [http://localhost:8080/health](http://localhost:8080/health) (or similar endpoint)
+- **Frontend:** Visit [http://localhost:5173](http://localhost:5173)
+- **Database:** Connect via `psql postgresql://grainlify:grainlify_dev_password@localhost:5432/grainlify`
+
+> [!NOTE]
+> If `run-dev.sh` fails with database connection errors, ensure Step 2 completed successfully.
