+# GoonScape
+
+A multiplayer isometric game inspired by Oldschool RuneScape, built with Go and Raylib.
+
+![GoonScape Screenshot](resources/screenshot.png)
+
+## Features
+
+- 3D isometric world with height-mapped terrain
+- Multiplayer support with client-server architecture
+- Pathfinding and click-to-move navigation
+- Global chat system with floating messages
+- Multiple character models
+- Background music
+
+## Prerequisites
+
+- Go 1.23 or higher
+- Raylib dependencies (see [raylib-go](https://github.com/gen2brain/raylib-go#requirements))
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone https://gitea.boner.be/bdnugget/goonscape.git
+cd goonscape
+```
+
+2. Install dependencies:
+```bash
+go mod tidy
+```
+
+3. Build and run:
+```bash
+go run main.go
+```
+
+## Controls
+
+- **Mouse Click**: Move to location
+- **T**: Open chat
+- **Enter**: Send chat message
+- **Escape**: Cancel chat/Close game (it does both of these at the same time so gg)
+- **Arrow Keys**: Rotate camera
+- **Mouse Wheel**: Zoom in/out
+
+## Configuration
+
+Server connection can be configured using command-line flags:
+
+```bash
+# Connect to default server (boner.be:6969)
+go run main.go
+
+# Connect to local server
+go run main.go -local
+
+# Connect to specific server
+go run main.go -addr somehost        # Uses somehost:6969
+go run main.go -addr somehost:6970   # Uses somehost:6970
+```
+
+Note: The `-local` flag is a shorthand for `-addr localhost:6969` and cannot be used together with `-addr`.
+
+## Building Release Binaries
+
+The project uses Docker to create consistent builds across platforms. To build release binaries:
+
+1. Build the Docker image (only needed once):
+```bash
+sudo docker build -t goonscape-builder -f Dockerfile.build .
+```
+
+2. Create release builds:
+```bash
+sudo docker run -v $(pwd):/build goonscape-builder
+```
+
+This will create zip files in the `build` directory for:
+- Windows (64-bit): `goonscape-windows-amd64-v1.0.0.zip`
+- Linux (64-bit): `goonscape-linux-amd64-v1.0.0.zip`
+
+Each zip contains the binary and all required assets.
+
+## Development
+
+The project uses Protocol Buffers for network communication. If you modify the `.proto` files, regenerate the Go code with:
+```bash
+protoc --go_out=. goonserver/actions/actions.proto
+```
