+## Quick Start with Docker (Pre-built Image)
+
+Run the latest pre-built image without cloning or building:
+
+### 1. Create the Docker Compose file
+
+```bash
+services:
+  postgres:
+    image: postgres:16-alpine
+    container_name: excalidraw-postgres
+    restart: unless-stopped
+    environment:
+      POSTGRES_USER: ${POSTGRES_USER:-excalidraw}

+
+### 2. Set Environment Variables
+
+**For Dokploy/CasaOS:** Configure these in the UI under Environment Variables.
+
+**For CLI/Terminal:** Create a `.env` file:
+
+```bash
+cat > .env << EOF
+# Required: Generate with: openssl rand -base64 32
+JWT_SECRET=your-secure-random-string-min-32-chars
+
+# Optional: Change defaults or leave as-is
+POSTGRES_USER=excalidraw
+POSTGRES_PASSWORD=excalidraw
+POSTGRES_DB=excalidraw
+PORT=3002
+
+# Optional: GitHub OAuth (for social login)
+GITHUB_CLIENT_ID=
+GITHUB_CLIENT_SECRET=
+
+# Optional: Generic OIDC (for SSO)
+OIDC_ISSUER_URL=
+OIDC_CLIENT_ID=
+OIDC_CLIENT_SECRET=
+
+EOF
+```
+
+### 3. Start the services
+
+```bash
+docker compose up -d
+```
+
+The app will be available at `http://localhost:3002` (or your configured `PORT`).
