+
+## Features
+
+### Google Cloud SDK
+
+The `google-cloud-sdk` feature installs the Google Cloud SDK and optional additional components.
+
+**NOTE:** Ubuntu 24.04 is currently **not** supported by this feature due to an issue with the `apt` package manager. The issue is being tracked [here]() and will be resolved once a fix is available.
+
+### ngrok
+
+The `ngrok` feature installs the ngrok binary; a globally distributed reverse proxy that secures, protects and accelerates your applications and network services, no matter where you run them.
