 This example demonstrates how to create a custom server on top of the SGLang Engine. We use [Sanic](https://sanic.dev/en/) as an example. The server supports both non-streaming and streaming endpoints.

+#### Steps
 
 1. Install Sanic:
 
-```bash
-pip install sanic
-```
+   ```bash
+   pip install sanic

 2. Run the server:
 
-```bash
-python custom_server

+   ```bash
+   python custom_server

 3. Send requests:
 
-```bash
-curl -X POST http://localhost:8000/generate  -H "Content-Type: application/json"  -d '{"prompt": "The Transformer architecture is..."}'
-curl -X POST http://localhost:8000/generate_stream  -H "Content-Type: application/json"  -d '{"prompt": "The Transformer architecture is..."}' --no-buffer
