-**Introduction**: 
+Azure Purview Scanning is a fully managed cloud service whose users can scan your data into your data estate (also known as your **catalog**). Scanning is a process by which the catalog connects directly to a data source on a user-specified schedule.
 
-TODO
+- Scan your data into your catalog
+- Examine your data
+- Extract schemas from your data
 
-## Getting started
+**Please rely heavily on the [service's documentation][catalog_product_documentation] and our [protocol client docs][protocol_client_quickstart] to use this library**

+## Getting started
 
 ### Install the package
 
-TODO
+Install the Azure Purview Scanning client library for .NET with [NuGet][client_nuget_package]:
+
+```
+dotnet add package Azure.Analysis.Purview.Scanning --prerelease
+```
 
 ### Prerequisites
 
-TODO
+- You must have an [Azure subscription][azure_subscription] and a [Purview resource][purview_resource] to use this package.
 
 ### Authenticate the client
 
-TODO
+#### Using Azure Active Directory
+
+This document demonstrates using [DefaultAzureCredential][default_cred_ref] to authenticate via Azure Active Directory. However, any of the credentials offered by the [Azure.Identity][azure_identity] will be accepted. See the [Azure.Identity][azure_identity] documentation for more information about other credentials.
+
+Once you have chosen and configured your credential, you can create instances of the `PurviewScanningClient`.
+
+```C#
+var credential = new DefaultAzureCredential();
+var client = new PurviewScanningClient(new Url("https://<my-account-name>.scanning.purview.azure.com"), credential);
+```
 
 ## Key concepts
 
-TODO
+### Protocol Methods
+
+Operations exposed by the Purview Scanning SDK for .NET use *protocol methods* to expose the underlying REST operations. You can learn more about how to use SDK Clients which use protocol methods in our [documentation][protocol_client_quickstart].

 ## Examples
 
-TODO
+The following section shows you how to initialize and authenticate your client, then list all of your data sources.
+
+### List All Data Sources
+
+```C#
+var credential = new DefaultAzureCredential();
+var client = new PurviewScanningServiceClient(new Uri("https://<my-account-name>.scanning.purview.azure.com"), credential);
+
+var response = await client.GetDataSourcesAsync();
+var responseDocument = JsonDocument.Parse(response.Content);
+Console.WriteLine(responseDocument.RootElement.GetProperty("value"));
+```
 
 ## Troubleshooting
 
-TODO
+### Setting up console logging
+The simplest way to see the logs is to enable the console logging.
+To create an Azure SDK log listener that outputs messages to console use AzureEventSourceListener.CreateConsoleLogger method.
+
+```C#
+// Setup a listener to monitor logged events.
+using AzureEventSourceListener listener = AzureEventSourceListener.CreateConsoleLogger();
+```
+
+To learn more about other logging mechanisms see [here][azure_core_diagnostics].
 
 ## Next steps
 
-TODO
+This client SDK exposes operations using *protocol methods*, you can learn more about how to use SDK Clients which use protocol methods in our [documentation][protocol_client_quickstart].
