It's a simple static webpage written in HTML displaying some informations about your server
Just git clone the repo and change the values of the server details inside the HTML ( as it's static, you directly have to modify the HTML )
As I run multiple servers I name them after anime girls ( Mai, Mugi, etc. ) and each server has its subdomain displaying information about it ( mai.rominou.moe, mugi.rominou.moe, etc. )
