+# Ray Coder Module
+
+This Coder module provides easy integration of Ray.io distributed computing framework into your Coder workspaces. It automatically sets up Ray with a dashboard interface and creates a dedicated Python virtual environment.
+
+## Features
+
+- 🚀 **Ray Dashboard**: Web-based interface for monitoring Ray clusters
+- 🐍 **Python Virtual Environment**: Isolated environment with Ray and dependencies
+- 📊 **Jupyter Integration**: Optional Jupyter kernel with Ray support
+- ⚙️ **Customizable**: Configurable Ray extras, packages, and settings
+- 🔧 **Auto-setup**: Automatic Ray installation and dashboard startup
+
+## Usage
+
+### Basic Usage
+
+```hcl
+module "ray" {
+  source   = "registry.coder.com/modules/ray-dashboard/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.main.id
+}
