Authorization for trademark use

Hello,

I would like to market some products as "stickers", "mug", "shirts" and so on, with the logo of some programming languages and Frameworks, including Codeigniter.

How it works? What I need to do and what I need to know?

I read this page https://www.codeigniter.com/help/legal, but I did not find answers regarding the use of the brand for commercial purposes

Thanks for listening!!!
