 ## Prerequisites
 
 - Go 1.23 or higher
+- GCC (for CGO/SQLite support)
+- OpenGL development libraries
 - Raylib dependencies (see [raylib-go](https://github.com/gen2brain/raylib-go#requirements))
 
 ## Installation
 
-1. Clone the repository:
+### Pre-built Binaries
+The easiest way to get started is to download the latest release from:
+```
+https://gitea.boner.be/bdnugget/goonscape/releases
+```
+Choose the appropriate zip file for your platform:
+- Windows: `goonscape-windows-amd64-v1.1.0.zip`
+- Linux: `goonscape-linux-amd64-v1.1.0.zip`
+
+Extract the zip and run the executable.
+
+### Quick Start
+For development:
+```bash
+# Run directly (recommended for development)
+go run main.go
+
+# Run with local server
+go run main.go -local
+```
+
+### Server Setup
+The server requires CGO for SQLite support:
+```bash
+# Enable CGO
+go env -w CGO_ENABLED=1
+
+# Clone and build server
+git clone https://gitea.boner.be/bdnugget/goonserver.git
+cd goonserver
+go build
+```
+
+### Client Installation
+Then install or build:
+```bash
+# Install the client
+go install gitea.boner.be/bdnugget/goonscape@latest
+```
+
+Or build from source:
 ```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
+go build
 ```
