+# Direct Routing Configuration
+
+For full instructions on how to build this code sample from scratch, look at [Quickstart: Direct Routing](https://docs.microsoft.com/azure/communication-services/quickstarts/telephony-sms/voice-routing-sdk-config?pivots=programming-language-csharp)
+
+## Prerequisites
+
+- An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/free/?WT.mc_id=A261C142F).
+- The latest version [.NET Core client library](https://dotnet.microsoft.com/download/dotnet-core) for your operating system.
+- An active Communication Services resource and connection string. [Create a Communication Services resource](https://docs.microsoft.com/azure/communication-services/quickstarts/create-communication-resource?tabs=windows&pivots=platform-net).
+
+## Code Structure
+
+- **./DirectRouting/Program.cs:** Core application code with manage phone numbers implementation.
+- **./DirectRouting/DirectRouting.csproj:** Project configuration file.
+
+## Before running sample code
+
+1. Open an instance of PowerShell, Windows Terminal, Command Prompt or equivalent and navigate to the directory that you'd like to clone the sample to.
+2. `git clone https://github.com/Azure-Samples/Communication-Services-dotnet-quickstarts.git`
+3. With the `Connection String` procured in pre-requisites, add it to the **DirectRouting/program.cs** file. Assign your connection string in line 3:
+  ```csharp
+  var connectionString = "endpoint=https://<RESOURCE_NAME>.communication.azure.com/;accesskey=<ACCESS_KEY>";
+  ```
+
+## Run Locally
+
+```console
+dotnet run
+```
