+Client library for epilot Data Management API
+
+Uses [`openapi-client-axios`](https://github.com/openapistack/openapi-client-axios)
+
+## Installation
+
+```bash
+npm install --save @epilot/data-management-client
+```
+
+## Usage
+
+```typescript
+import { getClient } from '@epilot/data-management-client';
+
+const dataManagementClient = getClient();
+// Example:
+// const res = await dataManagementClient.someOperation();
+```
+
+## Generate from OpenAPI
+
+Use the local OpenAPI source:
+
+```bash
+pnpm --filter @epilot/data-management-client run openapi:local && pnpm --filter @epilot/data-management-client run typegen
+```
+
+Or (if available) fetch from docs:
+
+```bash
+pnpm --filter @epilot/data-management-client run openapi && pnpm --filter @epilot/data-management-client run typegen
+```
