+# Azure Event Grid Publisher Client Module for Go
+
+[Azure Event Grid](https://learn.microsoft.com/azure/event-grid/overview) is a highly scalable, fully managed Pub Sub message distribution service that offers flexible message consumption patterns. For more information about Event Grid see: [link](https://learn.microsoft.com/azure/event-grid/overview).
+
+The client in this package can publish events to [Event Grid topics](https://learn.microsoft.com/azure/event-grid/concepts).
+
+> NOTE: This client does NOT work with Event Grid namespaces. Use the [`aznamespaces`][godoc_namespaces] module instead.
+
+Key links:
+- [Source code][source]
+- [API Reference Documentation][godoc]
+- [Product documentation](https://azure.microsoft.com/services/event-grid/)
+- [Samples][godoc_examples]
+
+## Getting started
+
+### Install the package
+
+Install the Azure Event Grid client module for Go with `go get`:
+
+```bash
+go get github.com/Azure/azure-sdk-for-go/sdk/messaging/eventgrid/azeventgrid
+```
+
+### Prerequisites
+
+- Go, version 1.18 or higher
+- An [Azure subscription](https://azure.microsoft.com/free/)
+- An Event Grid topic. You can create an Event Grid topic using the [Azure Portal](https://learn.microsoft.com/azure/event-grid/custom-event-quickstart-portal).
+
+### Authenticate the client
+
+Event Grid publisher clients authenticate using either:
+- A TokenCredential. An example of that can be viewed here: [ExampleNewClientWithSharedKeyCredential][godoc_example_newclient].
+- A shared key credential. An example of that can be viewed here: [ExampleNewClientWithSharedKeyCredential][godoc_example_newclientsk]
+- A Shared Access Signature (SAS). An example of that can be viewed here: [ExampleNewClientWithSharedKeyCredential][godoc_example_newclientsas].
+
+# Key concepts
+
+The client in this package can publish events to Azure Event Grid topics. Topics are published to using the [publisher.Client][godoc_publisher_client]. The topic
+you publish to will be configured to accept events of a certain format: EventGrid, CloudEvent or Custom. Separate functions are available on the publisher client for each format.
+
+# Examples
+
+Examples for various scenarios can be found on [pkg.go.dev][godoc_examples] or in the example*_test.go files in our GitHub repo for [azeventgrid][gh].
+
+# Troubleshooting
+
+### Logging
+
+This module uses the classification-based logging implementation in `azcore`. To enable console logging for all SDK modules, set the environment variable `AZURE_SDK_GO_LOGGING` to `all`. 
+
+Use the `azcore/log` package to control log event output.
+
+```go
+import (
+  "fmt"
+  azlog "github.com/Azure/azure-sdk-for-go/sdk/azcore/log"
+)
+
+// print log output to stdout
+azlog.SetListener(func(event azlog.Event, s string) {
+    fmt.Printf("[%s] %s\n", event, s)
+})
+```
+
+# Next steps
+
+More sample code should go here, along with links out to the appropriate example tests.
