+# CopilotKit <> Mastra Starter
+
+This is a starter template for building AI agents using [Mastra](https://mastra.ai) and [CopilotKit](https://copilotkit.ai). It provides a modern Next.js application with integrated AI capabilities and a beautiful UI.
+
+## Prerequisites
+
+- Node.js 18+
+- Any of the following package managers:
+  - npm (default)
+  - [pnpm](https://pnpm.io/installation)
+  - [yarn](https://classic.yarnpkg.com/lang/en/docs/install/)
+  - [bun](https://bun.sh/)
+
+## Getting Started
+
+1. Add your OpenAI API key
+
+```bash
+# you can use whatever model Mastra supports
+echo "OPENAI_API_KEY=your-key-here" >> .env
+```
+
+2. Install dependencies using your preferred package manager:
+
+```bash
+# Using npm (default)
+npm install
+
+# Using pnpm
+pnpm install
+
+# Using yarn
+yarn install
+
+# Using bun
+bun install
+```
+
+3. Start the development server:
+
+```bash
+# Using npm (default)
+npm run dev
+
+# Using pnpm
+pnpm dev
+
+# Using yarn
+yarn dev
+
+# Using bun
+bun run dev
+```
+
+This will start both the UI and agent servers concurrently.
+
+## Available Scripts
+
+The following scripts can also be run using your preferred package manager:
+
+- `dev` - Starts both UI and agent servers in development mode
+- `dev:ui` - Starts only the Next.js UI server
+- `dev:agent` - Starts only the Mastra agent server
+- `dev:debug` - Starts development servers with debug logging enabled
+- `build` - Builds the application for production
+- `start` - Starts the production server
+
+## Documentation
+
+- [Mastra Documentation](https://mastra.ai/en/docs) - Learn more about Mastra and its features
+- [CopilotKit Documentation](https://docs.copilotkit.ai) - Explore CopilotKit's capabilities
+- [Next.js Documentation](https://nextjs.org/docs) - Learn about Next.js features and API
