+## Overview
+
+mcpgen-cli generates a ready-to-run MCP server from an OpenAPI or Postman spec, so an existing API can be exposed to Claude, Cursor, and other MCP clients without hand-writing the integration layer.
+
+## Features
+
+- Generates a complete MCP server from OpenAPI or Postman input
+- Installable via `pip install mcpgen-cli`
+- [2-3 more real ones — auth handling, transports supported, output structure, whatever's actually true]
+
+## Usage
+
+```bash
+pip install mcpgen-cli
+```
+
+Generate from an OpenAPI specification:
+
+```bash
+mcpgen generate --input openapi.yaml --output ./mcp-server
+```
+
+Generate from a Postman collection:
+
+```bash
+mcpgen generate --input collection.json --output ./mcp-server
+```
