+
+The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio Code.
+
+1. Ensure you have downloaded and installed [Visual Studio Code](https://code.visualstudio.com/docs/setup/setup-overview)
+1. Install the [Teams Toolkit extension](https://marketplace.visualstudio.com/items?itemName=TeamsDevApp.ms-teams-vscode-extension)
+1. Select **File > Open Folder** in VS Code and choose this samples directory from the repo
+1. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
+1. Select **Debug > Start Debugging** or **F5** to run the app in a Teams web client.
+1. In the browser that launches, select the **Add** button to install the app to Teams.
+
+> If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.
