+# Supabase Plugin for FxSupport
+
+## Overview
+This plugin enables you to run Supabase, an open-source Firebase alternative, on your FxSupport system using Docker containers.
+
+## Features
+- **PostgreSQL Database**: Full-featured PostgreSQL database
+- **Authentication**: Built-in user authentication and authorization
+- **Instant APIs**: Auto-generated REST and GraphQL APIs
+- **Realtime Subscriptions**: Listen to database changes in real-time
+- **Storage**: Store and serve files
+- **Edge Functions**: Deploy serverless functions
+- **Studio Dashboard**: Web-based database management interface
+
+## Requirements
+- Linux OS (x86_64 or ARM64)
+- Minimum 2GB RAM (4GB recommended)
+- 10GB available disk space
+- Docker 20.10.0 or higher
+
+## Installation
+```bash
+./install.sh
+```
+This will:
+- Check system requirements
+- Install Docker if not present
+- Download Supabase Docker images
+- Configure environment variables
+- Set up firewall rules
+
+## Usage
+
+### Start Supabase
+```bash
+./start.sh
+```
+
+### Stop Supabase
+```bash
+./stop.sh
+```
+
+### Restart Supabase
+```bash
+./restart.sh
+```
+
+### Check Status
+```bash
+./status.sh
+```
+This displays:
+- Service status
+- Connection URLs
+- API keys
+- Database credentials
+
+### Uninstall
+```bash
+./uninstall.sh
+```
+**Warning**: This removes all data and configurations!
+
+## Access Points
+
+After starting, Supabase will be available at:
+- **API Gateway**: http://YOUR_PUBLIC_IP:8000
+- **PostgreSQL**: YOUR_PUBLIC_IP:5432
+
+
+## Security Considerations
+
+1. **Change default passwords**: Update all default credentials after installation
+2. **Configure SSL**: For production use, set up SSL certificates
+3. **Firewall rules**: Ensure only necessary ports are exposed
+4. **API Keys**: Keep your service keys secure and never expose them publicly
+
+## Network Configuration
+
+The plugin automatically:
+- Detects your public IP address
+- Configures Supabase to be accessible externally
+- Opens required firewall ports (if UFW is installed)
+
+## Troubleshooting
+
+### Services not starting
+```bash
+docker compose logs -f
+```
+
+### Reset configuration
+```bash
+./stop.sh
+cd /opt/supabase
+rm .env
+./install.sh
+```
+
+### Check Docker status
+```bash
+docker ps
+docker compose ps
+```
