CentOS docs - May 2020 - Introduction

Hello! My name is Tomas Tomecek and I work for Red Hat.

I am a product owner of packit project [1]. We are planning to use
packit and unpacked-sources style of repos for contributions to centos
stream and this is something I'd love to document on the wiki.

Cheers!
