-To keep track of the progress of your Unity Simulation run, you will need to use Unity Simulation's command-line interface (USimCLI). Detailed instructions for USimCLI are provided [here](https://github.com/Unity-Technologies/Unity-Simulation-Docs/blob/master/doc/quickstart.md#download-unity-simulation-quickstart-materials). For the purposes of this tutorial, we will only go through the most essential commands, which will help us know when our Unity Simulation run is complete and where to find the produced dataset.

-As seen above, each run has a name, an ID, a creation time, and a list of executions. Note that each "run" can have more than one "execution", as you can manually execute runs again using USimCLI.

 You can also obtain a list of all the builds you have uploaded to Unity Simulation using the `usim get builds` command.
