+# Umami Analytics Setup
+
+This repository contains a **self-hosted, privacy-first analytics setup using Umami**.
+It allows your organization to track user behavior, analyze traffic, and make informed decisions while maintaining full visitor privacy and data ownership.
+
+---
+
+## Requirements
+
+* Server with **Node.js ≥ 18.17**
+* **PostgreSQL ≥ 12.14** (or MySQL ≥ 8.0)
+* **Docker & Docker Compose**
+* Minimum **1GB RAM** recommended
+
+> ⚠️ This setup should run on a separate server. Your main application server may not meet the Node.js/PostgreSQL requirements.
+
+---
+
+## Setup Instructions
+
+### 1. Copy environment variables
+
+```bash
+cp .env.example .env
+```
+
+### 2. Edit `.env`
+
+* Update the database credentials (`DATABASE_URL`)
+* Set a secure `APP_SECRET`
+
+### 3. Start the services
+
+```bash
+docker compose up -d
+```
+
+This will start:
+
+* **Umami app**
+* **PostgreSQL database**
+
+### 4. Access the dashboard
+
+Open in your browser:
+
+```
+http://<server-ip>:3000
+```
+
+* Create an **admin account**
+* Add your **websites** to start tracking
+
+### 5. Add tracking script to your website
+
+```html
+<script async src="http://<server-ip>:3000/script.js" data-website-id="YOUR_WEBSITE_ID"></script>
+```
+
+* Replace `<server-ip>` with your server domain or IP
+* Replace `YOUR_WEBSITE_ID` with the ID shown in the Umami dashboard
+
+---
+
+## Notes
+
+* This setup runs **independently** of the main application server
+* **All visitor data is private** and stored only in your database
+* You can **scale or back up the database** as needed
+* For production, consider using **HTTPS** and a **custom domain**
+* This setup is ready for deployment once a server is available
