+# Getting Started with Hello World Office add-in Sample
+
+Office add-ins are integrations built by third parties into Office by using our web-based platform.
+
+Now you have the ability to create a single unit of distribution for all your Office applications by using the same manifest format and schema, based on the current JSON-formatted MetaOS manifest.
+
+## This sample illustrates
+
+- How Office add-in of Word, Excel, Powerpoint, Outlook share the same JSON manifest in one project.
+
+## Prerequisites to use this sample
+
+- [Node.js](https://nodejs.org/), supported versions: 18, 20
+- Edge installed for debugging Office add-in.
+- Office for Windows: Beta Channel. Follow [this link](https://github.com/OfficeDev/TeamsFx/wiki/How-to-switch-Outlook-client-update-channel-and-verify-Outlook-client-build-version) for information about how to update channels and check your Office client build version.
+- An M365 account. If you do not have M365 account, apply one from [M365 developer program](https://developer.microsoft.com/en-us/microsoft-365/dev-program)
+- [Teams Toolkit Visual Studio Code Extension](https://aka.ms/teams-toolkit) version 5.11.0 and higher or [Teams Toolkit CLI](https://aka.ms/teams-toolkit-cli)
+
+## Minimal path to awesome
+
+### Debug Office add-in
+
+- Please note that the same M365 account should be used both in Teams Toolkit and Office Applications (Word, Excel, Powerpoint, Outlook).
+- From Visual Studio Code only: use the `Run and Debug Activity Panel` in Visual Studio Code, select `Debug in Excel Desktop (Edge Chromium)`, and click the `Run and Debug` green arrow button. Please run VSCode as administrator if localhost loopback for Microsoft Edge Webview hasn't been enabled. Once enbaled, administrator priviledge is no longer required.

+
+   Once the Excel app is open, you can select the option to show a task pane.
+   ![Excel add-in show taskpane](./assets/excel-ribbon.png)
+
+   The taskpane should look as shown in the following image.
+   ![Excel add-in task pane opened](./assets/thumbnail.png)
+
+   Other Office Applications share the same behavior.
+
+### Edit the manifest
+
+You can find the app manifest in `./appPackage` folder. The folder contains one manifest file:
+
+- `manifest.json`: Manifest file for Office add-in running locally.
+
+You may add any extra properties or permissions you require to this file. See the [schema reference](https://docs.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema) for more information.
+
+### Deploy and publish
+
+Currently unified manifest of Office add-in is in public preview, so it does not support deploy and publish.
+
+### Validate manifest file
+
+To check that your manifest file is valid:
+
+- From Visual Studio Code: open the command palette and select: `Teams: Validate Application` and select `Validate using manifest schema`.
+- From Teams Toolkit CLI: run command `teamsapp validate` in your project directory.
