+## Overview
+
+Thunder Server is an **experimental** companion service for [Thunder](https://github.com/thunder-app/thunder) that handles push notifications for both UnifiedPush and Apple Push Notification Service (APNs).
+
+## Features
+
+- **Push Notifications**: Supports both UnifiedPush and Apple Push Notification Service (APNs)
+- **Multi-Account Support**: Polls and delivers notifications for multiple accounts
+- **Docker-Ready**: Pre-configured Docker containers for easy deployment
+
+## Quick Setup Guide
+
+A docker compose configuration is provided for quick deployment. For custom deployments, docker images are available via GitHub.
+
+### Setup
+
+```bash
+# Clone the repository
+git clone https://github.com/thunder-app/thunder-server.git
+cd thunder-server
+
+# Copy and configure environment variables
+cp example.env .env
+
+# Start the server and database
+docker-compose up -d
+```
+
+The server will be available at `http://localhost:2831` by default.
+
+## Environment Configuration
+
+Configure your environment by copying `example.env` to `.env` and updating the following settings:
+
+### Application Settings
+```bash
+APP_PORT=2831
+```
+
+### Database Configuration
+```bash
+POSTGRES_USER=postgres
+POSTGRES_PASSWORD=password
+POSTGRES_HOSTNAME=postgres
+POSTGRES_PORT=5432
+POSTGRES_DATABASE=thunder_database
+```
+
+### Apple Push Notifications (APNs)
+```bash
+APNS_KEY_ID=your_key_id                     # Your Apple Developer Key ID
+APNS_TEAM_ID=your_team_id                   # Your Apple Developer Team ID
+APNS_APP_BUNDLE_ID=com.example.thunder      # Your app's bundle identifier
+```
+
+> **Note**: For APNs to work, you'll need to configure your Apple Developer account and obtain the necessary certificates.
