Hi. 

To begin with, I would suggest that you start by downloading our nRF5 SDK for Mesh.
In the Mesh SDK we have examples that can get you started, where the Light Switch examples might be the best place to start. 
This example demonstrates the mesh ecosystem that contains devices acting in two roles: Provisioner role and Node role (also referred to as provisionee role). It also demonstrates how to use Mesh models by using the Generic OnOff model in an application.

Documentation to the nRF5 SDK for Mesh can be found here. You can find information about the examples and how to test them in the documentation. 

Note that you can also use your smartphone and the nRF Mesh app to act as the provisioner. 
Here is a blog-post explaining the nRF Mesh app:
