 * **Action**: Download and install [Docker Desktop](https://www.docker.com/products/docker-desktop)
 * **Action**: Open a command line interface (Command Prompt on Windows, Terminal on Mac OS, etc.) and type the following command to run the Dataset Insights Docker image: 
-`docker run -p 8888:8888 -v <path to synthetic data>:/data -t unitytechnologies/datasetinsights:latest`, where the path to data is what we earlier found in Unity's console messages.
+`docker run -p 8888:8888 -v "<path to synthetic data>:/data" -t unitytechnologies/datasetinsights:latest`, where the path to data is what we earlier found in Unity's console messages.
 
 This will download a Docker image from Unity. If you get an error regarding the path to your dataset, make sure you have not included the enclosing `<` and `>` in the path and that the spaces are properly escaped.
