+## Prerequisites
+
+Before you begin, ensure the following are in place.
+
+| Tool | Minimum Version | Install |
+| ---- | --------------- | ------- |
+| [Salesforce CLI (`sf`)](https://developer.salesforce.com/tools/salesforcecli) | v2+ | `npm install -g @salesforce/cli` |
+| [Node.js](https://nodejs.org/) | v22+ | [nodejs.org](https://nodejs.org/) |

+
+Verify your Salesforce CLI version with:
+
+```bash
+sf --version
+```
+
+---
+
+## Quick Start
+
+Run these commands from this sample directory:
+
+```bash
+sf org login web --alias <alias>
+sf project deploy start --source-dir force-app --target-org <alias>
+```
+
+Replace `<alias>` with your target org alias or username.
+
+---
+
+## Step-by-Step Setup
+
+Use this section if you prefer to run each step manually.
+
+This project is metadata-first and does not require a local UI build step for deployment.
+
+### 1. Authenticate Your Org
+
+Log in to your target org using the Salesforce CLI:
+
+```bash
+sf org login web --alias <alias>
+```
+
+To verify authentication:
+
+```bash
+sf org display --target-org <alias>
+```
+
+If you are working with a sandbox, use:
+
+```bash
+sf org login web --alias <alias> --instance-url https://test.salesforce.com
+```
+
+### 2. Deploy Metadata
+
+Deploy the rental app Digital Experience metadata:
+
+```bash
+sf project deploy start \
+  --source-dir force-app/main/default/digitalExperiences \
+  --target-org <alias>
+```
+
+---
+
+## Testing in the Playground App
+
+After deploying your metadata, you can preview the app on a mobile device using the Salesforce Mobile Playground.
+
+1. In VS Code, open the Command Palette with **Cmd+Shift+P** and run:
+
+   ```
+   SFDX: Open in Live Preview
+   ```
+
+2. A QR code will appear — scan it with your device and follow the on-screen instructions to launch the app in the Playground.
