 This is an example that shows how to use [Rerun](https://github.com/rerun-io/rerun)'s C++ API to log and view VRS files.
 
+## Installing the Rerun viewer
+The Rerun C++ SDK works by connecting to an awaiting Rerun Viewer over TCP.
+
+#### Building from source
+* [Install `cargo`](https://rustup.rs/)
+* `cargo install rerun-cli`
+
+#### Using `pip`
+* `pip install rerun-sdk`
+
+### Running the Rerun viewer
+Just type `rerun` and the rerun viewer should show up. Then it is time to run this example!
