+# Redis Test Environments - Connection Guide
+
+This document lists all available Redis environments for testing RedisInsight.
+
+## 🚀 Quick Start
+
+### 1. Start All Redis Services
+```bash
+cd tests/e2e
+docker-compose -f rte.docker-compose.yml up -d
+```
+
+### 2. Start VPN (Required for Clusters and Sentinel)
+```bash
+docker-compose -f rte.networks.docker-compose.yml -f vpn.docker-compose.yml up -d
+```
+
+### 3. Connect to VPN
+- **Profile**: `tests/e2e/rte/openvpn/test.ovpn`
+- **Import** into your OpenVPN client and Connect
+- **Verify**: `ping 172.31.100.221` should work
+
+### 4. Ready to Test!
+All Redis environments are now accessible. See below for connection details.
+
+---
+
+## 📊 Available Environments Summary
+
+- **8 Standalone instances** (different versions and configurations) - No VPN needed
+- **3 Cluster configurations** (plain, RediSearch, RedisGears) - VPN required
+- **1 Sentinel setup** - VPN required
+- **1 Redis Enterprise** - No VPN needed (but needs 12GB+ RAM)
+- **1 SSH server** - For testing SSH tunneling
