-A TypeScript SDK for interacting with RxInferServer, providing type-safe access to all server endpoints and features.
+A TypeScript client for interacting with RxInferServer, providing type-safe access to its API endpoints.
+
+## About RxInferServer
+
+RxInferServer is a Julia-based server that provides an API for performing probabilistic inference using the RxInfer.jl package. This client library allows you to interact with RxInferServer from TypeScript/JavaScript applications.
+
+### Key Features of RxInferServer
+- Probabilistic inference using message passing
+- Support for various probabilistic models
+- RESTful API interface
+- Real-time inference capabilities
 
 ## Installation
 
 ```bash
 npm install @lazydynamics/rxinfer-client
 ```
 
-## Documentation
+## Usage
+
+```typescript
+import { RxInferClient, pingServer } from '@lazydynamics/rxinfer-client';
 
-For detailed documentation and getting started guide, please visit our [official documentation](https://lazydynamics.github.io/RxInferClient.js/).
+// Create a client instance
+const client = await RxInferClient.create();
 
-The documentation includes:
-- Getting Started Guide
-- API Reference
-- Examples and Use Cases
-- Best Practices
-- Troubleshooting
+// Use the client to interact with RxInferServer
+const response = await pingServer({ client });
+console.log(response.data);  // { status: 'ok' }
+```
 
 ## Development
 
-For information about developing this package, please see our [Contributing Guide](CONTRIBUTING.md).
+### Prerequisites
+- Node.js (LTS version recommended)
+- RxInferServer running locally or accessible via network
+
+### Setting up RxInferServer
+1. Clone the RxInferServer repository:
+   ```bash
+   git clone https://github.com/lazydynamics/RxInferServer.git
+   cd RxInferServer
+   ```
+
+2. Build and start the server:
+   ```bash
+   make docker
+   make dev
+   ```
+
+   This will start RxInferServer on `http://localhost:8000`.
+
+### Building the Client
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Generate TypeScript client from OpenAPI specification:
+   ```bash
+   npm run generate
+   ```
+
+3. Build the package:
+   ```bash
+   npm run build
+   ```
+
+### Running Tests
+```bash
+npm test
+```
+
+Note: Tests require RxInferServer to be running locally.
