-TODO: Put a short description of the package here that helps potential users
-know whether this package might be useful for them.

-## Features
+- Serverless functions (AWS Lambda ...)
+- Cloudflare Workers 
+- Fastly Compute@Edge 
+- Client side web/mobile applications
+- WebAssembly
+- and other environments where HTTP is preferred over TCP.
 
-TODO: List what your package can do. Maybe include images, gifs, or videos.
+See
+[the list of APIs](https://docs.upstash.com/features/restapi#rest---redis-api-compatibility)
+supported.

+  final value2 = await redis.zrange('scores', 0, 100);
+  print(value1);
+
+  // list
