 ## Prepare Directories
 As you've now read, NextGen in a Box requires a standard directory structure. In this step we prepare that directory and will write data to it in the following steps.

 ## Validation
-We have now completed the required steps to generate the input data package for a NextGen simulation. As you can tell by now, there are many steps and thus many places to make a mistake. The `run-validator.py` script provides a quick way to check that the input data package contains the required files and that they are consistent to one another. See [here](https://github.com/CIROH-UA/ngen-datastream/tree/main/python#run_validatorpy) for an explanation of the validation.
