+# Azure Web PubSub extension of isolated-process Azure Functions client library for .NET
+
+This extension defines the function binding types and triggers in Azure Functions for .NET isolated-process, allowing you to easily write functions that respond to any event published to Web PubSub.
+
+## Getting started
+
+### Install the package
+
+Install the client library from [NuGet](https://www.nuget.org/):
+
+```dotnetcli
+dotnet add package Microsoft.Azure.Functions.Worker.Extensions.WebPubSub
+```
+
+### Prerequisites
+
+- An [Azure subscription][azure_sub].
+- An existing Azure Web PubSub service instance.
+
+### Authenticate the client
+
+Not applicable for the library. You should work with a client library to deserialize service requests in a friendly way.
+
+## Key concepts
+
+### Events
+
+Connect, Connected, Disconnected are system events indicate connection stage. And Connect is a blocking event that service will wait for the response to determine next action. Any error returned will drop the connection.
+
+User events are message event. It's also a blocking event which service is waiting for response. And server can return information in the response which will be sent to the caller directly.
+
+### WebPubSubEventRequest
+
+WebPubSubEventRequest, represents a abstract request come from service side. In detail, it should be ValidationRequest or one of the 4 events, which are ConnectEventRequest, ConnectedEventRequest, UserEventRequest and DisconnectedEventRequest. ValidationRequest represent the request for [Abuse Protection](https://github.com/cloudevents/spec/blob/v1.0.1/http-webhook.md#4-abuse-protection).
+
+### WebPubSubEventResponse
+
+WebPubSubEventResponse, represents a abstract response should return to service. In detail, it should be EventErrorResponse or one of the 2 blocking events, which are ConnectEventResponse and UserEventResponse.
+
+## Examples
+
+Check Microsoft.Azure.WebPubSub.AspNetCore for E2E using examples.
+
+## Troubleshooting
+
+You can also easily [enable console logging](https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/core/Azure.Core/samples/Diagnostics.md#logging) if you want to dig deeper into the requests you're making against the service.
+
+## Next steps
+
+Please take a look at the
+[samples][samples_ref]
+directory for detailed examples on how to use this library.
