+# ENET Gaming Backend
+
+A multiplayer game server written in C# using ENet for networking. 
+Designed to support mutiple of my LÖVE2D game experiments at once.

+
+## Technology Stack
+
+- **Language**: C# (.NET)
+- **Networking**: [ENet-CSharp](https://github.com/nxrighthere/ENet-CSharp) - reliable UDP multiplayer protocol
+- **Deployment**: Docker + Nomad
+- **Port**: `7777` (UDP, configurable)
+
+## Quick Start
+
+### Prerequisites
+
+- .NET 8.0 or later
+- ENet-CSharp (vendored or via NuGet)
+- Docker (for containerization)
+
+### Local Development
+
+```bash
+cd backend
+dotnet build
+dotnet run
+```
+
+The server will start and listen on `127.0.0.1:7777` by default.
+
+### Testing Connection
+
+With a LÖVE2D client configured to connect to `localhost:7777`:
+
+```bash
+love ../two_player_cleaning_game
+```
+
+## Configuration
+
+Server behavior is controlled via environment variables:
+
+```bash
+ENET_HOST=0.0.0.0              # Bind address
+ENET_PORT=7777                 # UDP port
+```

+- [ ] Set up C# project structure
+- [ ] Integrate ENet-CSharp dependency
+- [ ] Implement basic server startup
+- [ ] Define message protocol
+- [ ] Create player session management
+- [ ] Build Docker image
+- [ ] Test Nomad deployment
+- [ ] Implement game state synchronization
