Create Github pages Knowledge base

Create a Knowledge base portal using Github pages for Faveo Helpdesk Developer documentation something similar to [login to view URL] All the articles here are coming from here [login to view URL] We need a framework/theme with few sample articles added with documentation, demo on how this work and then we can add all the articles our-self. Give us option for professional styles/themes to choose one. If you want we can provide you HTML theme, we don't have experience with Github pages, how to convert this HTML themes into Github pages. We are technical people, just don't have enough time to spend on this R&d, we need some handling holding from where we can start this process and later manage this portal our self.
