-## Start the API server
+## Standalone vs. Server mode
 
-The API server exposes a REST API for launching and managing workflow runs:
+Arc has two modes:
 
-```bash
-./target/release/arc serve
-```
-
-This starts the server on `http://localhost:3000`. Demo mode is per-request — the web UI sends the `X-Arc-Demo: 1` header automatically when configured with `ARC_DEMO=1`.
-
-## Start the web frontend
-
-In a separate terminal, install dependencies and start the React dev server:
-
-```bash
-cd apps/arc-web
-bun install
-bun run dev
-```
-
-The web UI is available at `http://localhost:5173` and connects to the API server on port 3000.
+- **Standalone mode** — Run workflows directly from the CLI. This is what the quick start covers above.
+- **Server mode** — A REST API server with a web frontend for launching and managing workflow runs. See [Server Deployment](/administration/deploy-server) for details.
