 ### First time setup
 It is strongly recommended to run `local-setup.sh` right after cloning the repository. This will install the pre-commit git hook to run lint checks for your code. CI will also run these checks, but it's best to prevent CI failures by running the checks locally.
+To run a specific module's test app, you might have to create a `local.properties` file in the root of the project, and add values according to that app's requirements.

 ### Creating a new module
 1. Run the `generate-module.sh` script. It will prompt you to enter a module name using [PascalCase](https://pl.wikipedia.org/wiki/PascalCase).
 After confirming the name, a new directory will be created with the basic module setup.
