Create our theme

Hello, gentlemen
I want to create a custom theme using the colours of my business. I already found the instructions and know how to do that. But there’s one thing I don’t understand:

To create an empty theme, run the following command from Matomo’s root directory:
./console generate:theme

What does that mean? How to do this?

You need to set up a development version of Matomo. Instructions for this are at Setting Up Matomo Development.

Once this is done, open a terminal or console application and navigate to the root folder where you installed Matomo, and execute the command “./console generate:theme”
