How to proceed HomtKit Accessory certification

Dear Forum,

I am trying to understand how to start Accessory certification.

Right now when I see the HomeKit certification Process, I see like below.

Accessory Certification

- Submit materials, including HomeKit Product Compliance Questionnaire


But there is no document explaining what are the materials and what are the questionnaire.

Could someone please explain where to start,

You will need an MFI license, you need to sign up for that before you can certify an accessory
