 tox -e examples
 ```
 
+[Dapr Mechanical Markdown](https://github.com/dapr/mechanical-markdown) is used to test the examples.
+
+If you need to run the examples against a pre-released version of the runtime, you can use the following command:
+- Get your daprd runtime binary from [here](https://github.com/dapr/dapr/releases) for your platform.
+- Copy the binary to your dapr home folder at $HOME/.dapr/bin/daprd.
+Or using dapr cli directly: `dapr init --runtime-version <release version>`
+- Now you can run the example with `tox -e examples`.
