+# Contributing to GrowthBook MCP Server
+
+Thank you for your interest in contributing! Follow these steps to work locally and test your changes:
+
+## Local Development Setup
+
+1. **Clone the repository**
+
+   ```sh
+   git clone https://github.com/YOUR_USERNAME/growthbook-mcp.git
+   cd growthbook-mcp
+   ```
+
+2. **Install dependencies**
+
+   ```sh
+   pnpm install
+   ```
+
+3. **Build the project**
+
+   Use TypeScript to generate the build:
+
+   ```sh
+   npx tsc
+   ```
+
+   This will output the compiled JavaScript files to the `dist/` directory (or as configured in `tsconfig.json`).
+
+4. **Add the server to your AI tool**
+
+When configuring your MCP client (e.g., Cursor, VS Code, Claude Desktop), use the absolute path to your local build. Example JSON config:
+
+   ```json
+   {
+     "mcpServers": {
+       "growthbook": {
+         "command": "node",
+         "args": ["/absolute/path/to/growthbook-mcp/dist/index.js"],
+         "env": {
+           "GB_API_KEY": "your-api-key",
+           "GB_USER": "your-name",
+           "GB_API_URL": "your-api-url",
+           "GB_APP_ORIGIN": "your-app-origin"
+         }
+       }
+     }
+   }
+   ```
+
+Replace `/absolute/path/to/growthbook-mcp/dist/index.js` with the actual path on your machine. If you're testing with a local version of GrowthBook, be sure to update environment variables to point to your local install.
+
+GrowthBook MCP is now ready to use 🤖
