One question @oldfly and @rafaelnovello, is there a plan that we move all these documents under Apache? Not in this PR for sure, just asking.

Hi @Wei-1 , we are still discussing about this, but I think it's better to bring these docs to apache infrastructure. Please feel free to suggest anything, We are new to the community and we have many things to learn. Thanks!!!

I recognize that we will have another repository in ASF group for Marvin-AI website from the dev mails.
So these resources will be put to that website repo, and the links will be pointing to those new resources when it is ready right?
Is anyone working on the website yet?
I can help if needed.

[oldfly]

Yes, exactly! We need your help for sure.
I'll check the situation of the website repository and warn you when everything is ready.

Hello @Wei-1 , i have created the repo for website: "https://gitbox.apache.org/repos/asf?p=incubator-marvin-website.git" and pushed the apache website template into it.
What should we do now? Restructure the original marvin website code by adapting the template?
