+# Quickstart: deploy your project to Azure using GitHub Copilot App Modernization for .NET
+
+This quickstart shows you how to deploy your project to Azure when you use [GitHub Copilot app modernization for .NET (Preview)](https://aka.ms/appmod-dotnet-marketplace).
+In code development, developers often need to deploy their project to a cloud environment for testing. Our tools help deploy your migrated project to Azure and fix any deployment errors in the process.
+
+## Prerequisites
+
+Before you begin, ensure you have:
+
+- A GitHub account with [GitHub Copilot](https://github.com/features/copilot) enabled (Pro, Pro+, Business, or Enterprise plan required)
+- [Visual Studio 2022](https://visualstudio.microsoft.com/downloads/) version 17.14.7 or later
+- Agent mode enabled for GitHub Copilot in Visual Studio ([Learn how](/visualstudio/ide/copilot-agent-mode))
+
+### Sign-in to GitHub Copilot
+
+GitHub Copilot is a dependency of the App Modernization Extension and experience. Make sure you're signed-in to GitHub Copilot inside Visual Studio.
+
+1. Select the Copilot icon at the top of Visual Studio to open the GitHub Copilot pane.
+1. Follow the UI prompts to sign-in to Copilot.
+
+For more information, see [Set up GitHub Copilot in Visual Studio](/visualstudio/ide/visual-studio-github-copilot-install-and-states).
+
+## Install the GitHub Copilot app modernization extension
+
+To complete the steps ahead, you need to install the GitHub Copilot app modernization for .NET (Preview) Visual Studio extension.
+
+1. Inside Visual Studio, navigate to `Extensions` > `Manage Extensions`.
+1. Search for **GitHub Copilot app modernization for .NET** in the marketplace.
+1. On the extension page, select **Install**.
+1. Follow the notification bar prompts to close Visual Studio and complete the installation.
+1. Relaunch Visual Studio after installation.
+
+You can also view the [GitHub Copilot app modernization for .NET (Preview)](https://aka.ms/appmod-dotnet-marketplace) extension directly on the extension marketplace.
+
+For more information, see [Find, install, and manage extensions for Visual Studio](/visualstudio/ide/finding-and-using-visual-studio-extensions).
+
+## Deploy your project
+
+App Modernization for .NET deployment helps you deploy your migrated app to an Azure environment. Follow these steps to start your deployment process:
+
+1. In Visual Studio, open your migrated project.
+
+2. Start the deployment using one of the following approaches:
+    * Deploy your project after completing your migration task. Copilot will ask you if you would like to deploy your project to Azure upon completing a migration task. Instructing Copilot to continue will start the deployment process.
+
+    :::image type="content" source="media/start-deploy.png" alt-text="A screenshot showing how to start the deployment process in GitHub Copilot.":::
+
+    * Deploy prompt.
+      
+      You can input the following prompt in Copilot chat to deploy your project to Azure.
+      
+      *Scan my project to identify all Azure-relevant resources, programming languages, frameworks, dependencies, and configuration files needed for deployment, and develop an architecture diagram for me using #appmod-generate-architecture-diagram. Based on that diagram, help me develop and execute a plan using #appmod-get-plan to deploy my project to Azure. deployTool: azcli, hosting service: non-aks.*

+
+3.	After you start the deployment, GitHub Copilot might ask for your approval to use tools in the Model Context Protocol (MCP) server. Grant permission when prompted.
+
+4.	GitHub Copilot will create a plan.copilot.md file in the.azure folder. This file explains the overall deployment plan including deployment goal, project information, Azure resource architecture, Azure resources, and execution steps. 
+
+5.	Edit the file directly or ask GitHub Copilot to edit to customize your deployment before proceeding.
+
+6.	Once you are satisfied with the plan, instruct GitHub Copilot to continue.
+
+7.	GitHub Copilot follows the plan and executes the deployment process.
+
+## Notes
+* We recommend using Claude Sonnet 4 or later models for the best results.
+* It might take Copilot a few iterations to correct deployment errors.
