+
+## Features
+
+This sample illustrates the following concepts on top of the SharePoint Framework:
+
+* Using AadTokenProvide to consume Yammer API.
+* How to get User/Group information from Yammer.
+* How to post a praise to Yammer.
+* React Hooks
+* Using async / await for the async calls
+* Office UI fabric components
+* Can be installed on Microsoft Teams as Personal app or a team tab
+
+## Configuration
+
+To get access to Yammer API, we need to add the required permission to “SharePoint Online Client Extensibility Web Application Principal” application:
+
+* Navigate to Azure portal.
+* Search for App Registration at top search box.
+* Select “SharePoint Online Client Extensibility Web Application Principal“
+* Select “API permissions” from left navigation.
+* Click “Add a permission“.
+* Select Yammer.
+* Select “User_Impersonation” from delegated permissions.
+* Click “Add permissions“.
+* Click “Grant admin consent” button.
+* Select “Yes, add other granted permissions to configured permissions“
+* Click “Save and continue“.
+* Click “Grant admin consent“.
+* Select “Yes“.
+
+Bundle and package the solution, deploy it to app catalog, then add the web part to any pages in SharePoint or add to your Teams.
+
+Read my blog post for more information from [here](https://github.com/SharePoint/sp-dev-fx-webparts/tree/master/samples/react-yammer-api).
