 Extract the `ShareX-15.0.0-portable.zip` into the resources directory, so that the
 `ShareX.exe` is located under `{path-to-rancher-desktop}\resources\ShareX\ShareX.exe`.
 
+If the script is just hanging while taking the first screenshot, you can try to:
+
+1. Set the `RD_ENV_SCREENSHOT_SLEEP` environment variable

+2. If the first option doesn't resolve the issue, try to disable the ShareX sound and
+   toast effects.
+
+   In order to do so, uncheck `Play sound after capture is made`, `Play sound after
+   task is completed` and `Show toast notification after task is completed` at: ShareX
+   menu -> Task Settings -> General -> Notifications.
