+### Quickstarts and tutorials
+
+Want to put the Dapr <topic> API to the test? Walk through the following quickstart and tutorials to see <topic> in action:
+
+| Quickstart/tutorial | Description |
+| ------------------- | ----------- |
+| [<topic> quickstart](link) | Description of the quickstart. |
+| [<topic> tutorial](link) | Description of the tutorial. |
+
+### Start using <topic> directly in your app
+
+Want to skip the quickstarts? Not a problem. You can try out the <topic> building block directly in your application. After [Dapr is installed](link), you can begin using the <topic> API, starting with [the <topic> how-to guide](link).
